.Sh "Definitions"
.IP \*(Sc
The literal character \fIc\fP.
.IP \*(Cc
A single (required) character.
.IP \*(Ps
A single (usually optional) numeric parameter, composed of one of more digits.
.IP \*(Pm
A multiple numeric parameter composed of any number of single numeric
parameters, separated by \*; character(s).
Individual values for the parameters are listed with \*(Ps .
.IP \*(Pt
A text parameter composed of printable characters.
.
.Sh "C1 (8-Bit) Control Characters"
.LP
The \fIxterm\fP program recognizes both 8-bit and 7-bit control characters.
It generates 7-bit controls (by default) or 8-bit if S8C1T is enabled.
The following pairs of 7-bit and 8-bit control characters are equivalent:
.St
.IP \\*(Es\\*D
Index (\*(ID is 0x84).
.IP \\*(Es\\*E
Next Line (\*(Nl is 0x85).
.IP \\*(Es\\*H
Tab Set (\*(Ht is 0x88).
.IP \\*(Es\\*M
Reverse Index (\*(RI is 0x8d).
.IP \\*(Es\\*N
Single Shift Select of G2 Character Set (\*(S2 is 0x8e).  This affects next character only.
.IP \\*(Es\\*O
Single Shift Select of G3 Character Set (\*(S3 is 0x8f).  This affects next character only.
.IP \\*(Es\\*P
Device Control String (\*(Dc is 0x90).
.IP \\*(Es\\*V
Start of Guarded Area (\*(Sg is 0x96).
.IP \\*(Es\\*W
End of Guarded Area (\*(Eg is 0x97).
.IP \\*(Es\\*(XX
Start of String (\*(SS is 0x98).
.IP \\*(Es\\*Z
Return Terminal ID (DECID is 0x9a).
Obsolete form of \*(Cs\*c (DA).
.IP \\*(Es\\*([[

.LP
These control characters are used in the vtXXX emulation.
.
.Sh "VT100 Mode"
.LP
Most of these control sequences are standard VT102 control sequences,
but there is support for later DEC VT terminals (i.e., VT220, VT320, VT420),
as well as ISO 6429 and \fIaixterm\fP color controls.
The only VT102 feature not supported is auto-repeat,
since the only way X provides for this will affect all windows.
There are additional control sequences to provide
\fIxterm-\fPdependent functions, such as the scrollbar or window size.
Where the function is specified by DEC or ISO 6429, the code assigned
to it is given in parentheses.
The escape codes to designate and invoke
character sets are specified by ISO 2022; see that document for a
discussion of character sets.

.sP
If a "?" is given rather than a name or RGB specification,

.Sh "Alt and Meta Keys"
.LP
Many keyboards have keys labeled "Alt".
Few have keys labeled "Meta".
However, \fIxterm\fP's default translations use the \fIMeta\fP modifier.
Common keyboard configurations assign the \fIMeta\fP modifier to an "Alt" key.
By using \fIxmodmap\fP one may have the modifier assigned to a different key,
and have "real" alt and meta keys.
Here is an example:
.DS B
! put meta on mod3 to distinguish it from alt
keycode 64 = Alt_L
clear mod1
add mod1 = Alt_L
keycode 115 = Meta_L
clear mod3
add mod3 = Meta_L
.DE
.lP
The \fBmetaSendsEscape\fP resource
(and \fBaltSendsEscape\fP if \fBaltIsNotMeta\fP is set)
can be used to control the way the \fIMeta\fP modifier applies to ordinary
keys unless the \fBmodifyOtherKeys\fP resource is set:
.IP
-
prefix a key with the \*(Es character.
.IP
-
shift the key from codes 0-127 to 128-255 by adding 128.
.lP
The table shows the result for a given character "x" with modifiers
according to the default translations with the resources set on or off.
This assumes \fBaltIsNotMeta\fP is set:

.Sh "PC-Style Function Keys"

If \fIxterm\fP does minimal translation of the function keys, it usually does this

.Sh "Sun-Style Function Keys"
.LP
The \fIxterm\fP program provides support for Sun keyboards more directly, by
a menu toggle that causes it to send Sun-style function key codes rather than VT220.
Note, however, that the \fIsun\fP and \fIVT100\fP emulations are not really
compatible.
For example, their wrap-margin behavior differs.
.lP
Only function keys are altered; keypad and cursor keys are the same.
The emulation responds identically.
See the xterm-sun terminfo entry for details.
.Sh "HP-Style Function Keys"
.LP
Similarly, \fIxterm\fP can be compiled to support HP keyboards.
See the xterm-hp terminfo entry for details.
.Sh "The Alternate Screen Buffer"
.LP
\fIXterm\fP maintains two screen buffers.
The normal screen buffer allows you to scroll back to view saved lines
of output up to the maximum set by the \fBsaveLines\fP resource.
The alternate screen buffer is exactly as large as the display,
contains no additional saved lines.
When the alternate screen buffer is active,
you cannot scroll back to view saved lines.
\fIXterm\fP provides control sequences and menu entries
for switching between the two.
.lP
Most full-screen applications use terminfo or termcap to obtain
strings used to start/stop full-screen mode,
i.e., \fIsmcup\fP and \fIrmcup\fP for terminfo,
or the corresponding \fIti\fP and \fIte\fP for termcap.
The \fBtiteInhibit\fP resource removes the \fIti\fP and \fIte\fP strings
from the TERMCAP string which is set in the environment for some platforms.
That is not done when \fIxterm\fP is built with terminfo libraries because
terminfo does not provide the whole text of the termcap data in one piece.
It would not work for terminfo anyway, since terminfo data is not passed
in environment variables;
setting an environment variable in this manner would have no effect on
the application's ability to switch between normal and alternate screen
buffers.
Instead, the newer private mode controls
(such as \*1\*0\*4\*9)
for switching between normal
and alternate screen buffers simply disable the switching.
They add other features such as clearing the display for the same reason:
to make the details of switching independent of the application that
requests the switch.
.
.Sh "Bracketed Paste Mode"
.LP
When bracketed paste mode is set,
pasted text is bracketed with control sequences
so that the program can differentiate pasted text from typed-in text.
When bracketed paste mode is set,
the program will receive:
   \*(Es [ 200 ~,
.br
followed by the pasted text, followed by
   \*(Es [ 201 ~.
.
.Sh "Title Modes"
.LP
The window- and icon-labels can be set or queried using control sequences.
As a VT220-emulator, \fIxterm\fP "should" limit the character encoding for
the corresponding strings to ISO-8859-1.
Indeed, it used to be the case (and was documented) that
window titles had to be ISO-8859-1.
This is no longer the case.
However, there are many applications which still assume that titles are
set using ISO-8859-1.
So that is the default behavior.
.lP
If \fIxterm\fP is running with UTF-8 encoding,
it is possible to use window- and icon-labels encoded using UTF-8.
That is because the underlying X libraries (and many, but not all)
window managers support this feature.
.lP
The \fButf8Title\fP X resource setting tells \fIxterm\fP to disable
a reconversion of the title string back to ISO-8859-1,
allowing the title strings to be interpreted as UTF-8.
The same feature can be enabled using the title mode control sequence
described in this summary.
.lP
Separate from the ability to set the titles,
\fIxterm\fP provides the ability to query the titles,
returning them either in ISO-8859-1 or UTF-8.
This choice is available only while \fIxterm\fP is using UTF-8 encoding.
.lP
Finally, the characters sent to, or returned by a title control
are less constrained than the rest of the control sequences.
To make them more manageable (and constrained), for use in shell scripts,
\fIxterm\fP has an optional feature which decodes the string from hexadecimal
(for setting titles) or for encoding the title into hexadecimal when querying
the value.
.
.Sh "Mouse Tracking"
.LP
The VT widget can be set to send the mouse position and other
information on button presses.
These modes are typically used by
editors and other full-screen applications that want to make use of
the mouse.
.lP
There are two sets of mutually exclusive modes:
.bP
mouse protocol
.bP
protocol encoding
.lP
The mouse protocols include
DEC Locator mode, enabled by the
DECELR \*(Cs\*(Ps\*s\*;\*(Ps\*s\*s\*(qu\*s\*z
control sequence, and is not described here
(control sequences are summarized above).
The remaining five modes of the mouse protocols
are each enabled (or disabled) by a different parameter in
the "DECSET \*(Cs\*?\*(Pm\*s\*h"
or
"DECRST \*(Cs\*?\*(Pm\*s\*l"
control sequence.
.lP
Manifest constants for the parameter values
are defined in \fBxcharmouse.h\fP as follows:
.
.DS B
#define SET_X10_MOUSE               9
#define SET_VT200_MOUSE             1000
#define SET_VT200_HIGHLIGHT_MOUSE   1001

#define SET_SGR_EXT_MODE_MOUSE      1006
#define SET_URXVT_EXT_MODE_MOUSE    1015
.DE
.br
The motion reporting modes are strictly \fIxterm\fP extensions, and are not
part of any standard, though they are analogous to the DEC VT200 DECELR
locator reports.
.lP
Normally,
parameters (such as pointer position and button number) for all mouse
tracking escape sequences generated by \fIxterm\fP
encode numeric parameters in a single character as
\fIvalue\fP+32.
For example, \*! specifies the value 1.
The upper left character position on the terminal is denoted as 1,1.
This scheme dates back to X10,
though the normal mouse-tracking (from X11) is more elaborate.
.lP
X10 compatibility mode sends an escape sequence only on button press,
encoding the location and the mouse button pressed.
It is enabled by specifying parameter 9 to DECSET.
On button press, \fIxterm\fP sends
\*(Cs\*M\*(Cb\*(Cx\*(Cy (6 characters).
.bP
\*(Cb is button\-1.
.bP
\*(Cx and \*(Cy are the x and y coordinates of the mouse when the
button was pressed.
.lP
Normal tracking mode sends an escape sequence on both button press and
release.
Modifier key (shift, ctrl, meta) information is also sent.
It is enabled by specifying parameter 1000 to DECSET.
On button press or release, \fIxterm\fP sends
\*(Cs\*M\*(Cb\*(Cx\*(Cy.
.bP
The low two bits of \*(Cb encode button information:
0=MB1 pressed, 1=MB2 pressed, 2=MB3 pressed, 3=release.
.bP
The next three bits encode the modifiers which were down when the button was
pressed and are added together:  4=Shift, 8=Meta, 16=Control.
Note however that the shift and control bits are normally unavailable
because \fIxterm\fP uses the control modifier with mouse for popup menus,
and the shift modifier is used in the default translations for button events.
The \fIMeta\fP modifier recognized by \fIxterm\fP is the \fImod1\fP mask,
and is not necessarily the "Meta" key (see \fIxmodmap\fP).
.bP
\*(Cx and \*(Cy are the x and y coordinates of the mouse event, encoded as
in X10 mode.
.lP
Wheel mice may return buttons 4 and 5.
Those buttons are represented by the same event codes
as buttons 1 and 2 respectively,
except that 64 is added to the event code.
Release events for the wheel buttons are not reported.
.lP
Mouse highlight tracking notifies a program of a button press, receives a
range of lines from the program, highlights the region covered by
the mouse within that range until button release, and then sends the
program the release coordinates.
It is enabled by specifying parameter 1001 to DECSET.
Highlighting is performed only for button 1, though other button events
can be received.
.sP
\fBWarning:\fP use of this mode requires a cooperating program or it will
hang \fIxterm.\fP
.sP
On button press, the same information as for normal tracking is
generated; \fIxterm\fP then waits for the program to send mouse
tracking information.
\fIAll X events are ignored until the proper escape sequence is
received from the pty:\fP
\*(Cs\*(Ps\*s\*;\*(Ps\*s\*;\*(Ps\*s\*;\*(Ps\*s\*;\*(Ps\*s\*T.
The parameters are \fIfunc, startx, starty, firstrow,\fP and \fIlastrow.\fP
\fIfunc\fP is non-zero to initiate highlight tracking and zero to abort.
\fIstartx\fP and \fIstarty\fP give the starting x and y location for
the highlighted region.
The ending location tracks the mouse, but
will never be above row \fIfirstrow\fP and will always be above row
\fIlastrow.\fP
(The top of the screen is row 1.)
When the button is released, \fIxterm\fP reports the ending position
one of two ways:
.bP
if the start and end coordinates are the same locations:
.br
\*(Cs\*t\*(Cx\*(Cy.
.bP
otherwise:
.br
\*(Cs\*T\*(Cx\*(Cy\*(Cx\*(Cy\*(Cx\*(Cy.
.br
The parameters are \fIstartx, starty, endx, endy, mousex,\fP and \fImousey.\fP
.RS
.IP \- 5
\fIstartx, starty, endx, \fPand\fI endy\fP give the starting and
ending character positions of the region.
.IP \- 5
\fImousex\fP and \fImousey\fP
give the location of the mouse at button up, which may not be over a
character.
.RE
.lP
Button-event tracking is essentially the same as normal tracking, but
\fIxterm\fP also reports button-motion events.
Motion events
are reported only if the mouse pointer has moved to a different character
cell.
It is enabled by specifying parameter 1002 to DECSET.
On button press or release, \fIxterm\fP sends the same codes used by normal
tracking mode.
.bP
On button-motion events, \fIxterm\fP adds 32 to the event code
(the third character, \*(Cb).
.bP
The other bits of the event code specify button and modifier keys as in normal mode.
For example, motion into cell x,y with button 1
down is reported as \*(Cs\*M\*@\*(Cx\*(Cy.
(\ \*@ = 32 + 0 (button 1) + 32 (motion indicator)\ ).
Similarly, motion with button 3
down is reported as \*(Cs\*M\*(cB\*(Cx\*(Cy.
(\ \*(cB = 32 + 2 (button 3) + 32 (motion indicator)\ ).
.lP
Any-event mode is the same as button-event mode, except that all motion
events are reported, even if no mouse button is down.
It is enabled by specifying 1003 to DECSET.
.lP
FocusIn/FocusOut can be combined with any of the mouse events since
it uses a different protocol.
When set, it causes \fIxterm\fP to send
\*(Cs\*I when the terminal gains focus, and
\*(Cs\*O when it loses focus.
.lP
The original X10 mouse protocol limits the \*(Cx and \*(Cy ordinates
to 223 (=255\ -\ 32).
\fIXterm\fP supports more than one scheme for extending this range,
by changing the protocol encoding:
.IP "UTF-8 (1005)"
This enables UTF-8 encoding for \*(Cx and \*(Cy under
all tracking modes, expanding the maximum encodable position from 223 to 2015.
For positions less than 95, the resulting output is identical under both modes.
Under extended mouse mode, positions greater than 95
generate "extra" bytes which will confuse applications which do not treat
their input as a UTF-8 stream.
Likewise, \*(Cb will be UTF-8 encoded,
to reduce confusion with wheel mouse events.
.IP
Under normal mouse mode, positions outside (160,94) result in
byte pairs which can be interpreted as a single UTF-8 character;
applications
which do treat their input as UTF-8 will almost certainly be confused
unless extended mouse mode is active.
.IP
This scheme has the drawback that the encoded coordinates will not
pass through \fIluit\fP unchanged, e.g., for locales using non-UTF-8 encoding.
.IP "SGR (1006)"
The normal mouse response is altered to use \*(Cs\*<
followed by semicolon-separated
encoded button value,
the \*(Cx and \*(Cy ordinates and a final character which
is \*M for button press
and \*m for button release.
.IP
The encoded button value in this case does not add 32 since
that was useful only in the X10 scheme for ensuring that the 
byte containing the button value is a printable code.
The modifiers are encoded in the same way.
A different final character is used for button release
to resolve the X10 ambiguity regarding which button was released.
.IP
The highlight tracking responses are also modified to an SGR-like format,
using the same SGR-style scheme and button-encodings.
.IP "URXVT (1015)"
The normal mouse response is altered to use \*(Cs
followed by semicolon-separated
encoded button value,
the \*(Cx and \*(Cy ordinates and final character \*M.
.IP
This uses the same button encoding as X10, but printing it as
a decimal integer rather than as a single byte.
.IP
However, \*(Cs\*M can be mistaken for DL (delete lines),
while the highlight tracking \*(Cs\*T can be mistaken for SD (scroll down),
and the Window manipulation controls.
For these reasons, the 1015 control is not recommended;
it is not an improvement over 1005.
.
