A single (required) character.

A single (usually optional) numeric parameter, composed of one of more digits.

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:

Most of these control sequences are standard VT102 control sequences,
but there is support for later DEC VT terminals (i.e., VT220 and VT320),
as well as ISO 6429 and \fIaixterm\fP color controls.
VT102 features not supported are
auto-repeat and blinking characters.
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.

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 five mutually exclusive modes, 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
#define SET_X10_MOUSE               9
#define SET_VT200_MOUSE             1000
#define SET_VT200_HIGHLIGHT_MOUSE   1001
#define SET_BTN_EVENT_MOUSE         1002
#define SET_ANY_EVENT_MOUSE         1003
.DE
.LP
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
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.
.
.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).
\*(Cb is button\-1.
\*(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.
The low two bits of \*(Cb encode button information:
0=MB1 pressed, 1=MB2 pressed, 2=MB3 pressed, 3=release.
The upper bits encode the modifiers which were down when the button was
pressed and are added together.  4=Shift, 8=Meta, 16=Control.
\*(Cx and \*(Cy are the x and y coordinates of the mouse event.
The upper left corner is (1,1).
.
.LP
Mouse hilite 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.
\fBWarning:\fP use of this mode requires a cooperating program or it will
hang \fIxterm.\fP
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 hilite 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: if the start and end coordinates are valid text
locations: \*(Cs\*t\*(Cx\*(Cy.  If either coordinate is past
the end of the line:
\*(Cs\*T\*(Cx\*(Cy\*(Cx\*(Cy\*(Cx\*(Cy.
The parameters are \fIstartx, starty, endx, endy, mousex,\fP and \fImousey.\fP
\fIstartx, starty, endx, \fPand\fI endy\fP give the starting and
ending character positions of the region.  \fImousex\fP and \fImousey\fP
give the location of the mouse at button up, which may not be over a
character.
.
.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.  On button-motion events, \fIxterm\fP adds 4 to the event code
(the third character, \*(Cb).
The low two bits of the event code encode the button information.
The third bit is set to indicate motion.
Additional bits specify 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 instead of just those that enter a new character cell.
It is enabled by specifying 1003 to DECSET.
