COMMAND
tag - displays lines matching target in different colour
SYNTAX
TAG [More|Less] [rtarget|Focus]
DESCRIPTION
The TAG command is similar to the <ALL> command, in that it allows
lines that match the specified target to be displayed. Where it
differs from <ALL> is that the lines that don't match are still
displayed, but the lines that do match are displayed in the colour
specified by <SET COLOUR> HIGHLIGHT.
This target consists of any number of individual targets
separated by '&' (logical and) or '|' (logical or).
For example, to display all lines in a file that contain the
strings 'ball' and 'cat' on the same line or the named lines
.fred or .bill, use the following command
TAG /ball/ & /cat/ | .fred | .bill
Logical operators act left to right, with no precedence for &.
TAG without any arguments displays all lines without any highlighting.
If <SET HIGHLIGHT> is not set to TAGGED, then if the specified 'rtarget'
is found, <SET HIGHLIGHT> is set to TAGGED.
When the optional 'More' argument is specified, all lines that match
the 'rtarget' are highlighted in addition to those already highlighted.
When the optional 'Less' argument is specified, all lines that match
the 'rtarget' and are currently highlighted have their highlighting
removed.
If 'FOCUS' is specified in place of 'rtarget', the <focus line> is
tagged.

XEDIT: N/A
KEDIT: Compatible.
FOCUS is a THE enhancement.

COMMAND
xedit - edit another file or switch to next file
SYNTAX
Xedit [file]
DESCRIPTION
The XEDIT command allows the user to edit another 'file'. The new file
is placed in the file <ring>. The previous file being edited remains
in memory. Several files can be edited at once, and all files
are arranged in a ring, with subsequent XEDIT commands moving through
the ring, one file at a time.
COMPATIBILITY
XEDIT: Does not provide options switches.
KEDIT: Does not provide options switches.

COMMAND
? - retrieve - return the next/prior command on the command line
SYNTAX
?[+|?...]
DESCRIPTION
The ? command returns the next or prior command from the command
line ring and displays it on the command line.
With the ['+'] argument, the next command in the command ring is
retrieved.
With no arguments, the previous command entered on the command
line is retrieved.
With multiple, concatenated ?s as argument, the pervious command
entered on the command line is retrieved corresponding to the
number of ?s entered.
For Example:
The command; ????? will retrieve the fifth last command entered.
COMPATIBILITY
XEDIT: Compatible. Support for +.
KEDIT: See below..
This command is bound to the up and down arrows when on the
command line depending on the setting of <SET CMDARROWS>.
