.SH "DESCRIPTION"
-.PP
-\fBselector\fP is a command line dynamic string selection. As you type
-a list of strings separated by ';', the display is updated in real
-time to show only the lines containing all the said strings.
+
+\fBselector\fP is a command line utility for dynamic string
+selection. As you type a list of strings separated by ";" or a regexp,
+the display is updated in real time to show only the lines containing
+all the said strings, or matching the regexp.
The main usage of selector is as an efficient search in the shell
command history. With the correct option, it will inject the selected
line into the virtual tty input buffer, hence allowing the user to
edit the line and execute it as a standard command.
-Keys corresponding to ASCII codes between ' ' and '~' add a character
-to the pattern string. The Delete key, Backspace key, ^D and ^H delete
-one character from the pattern string.
+Selector is also a good tool to test regexps, or a way to display
+menus. The -x option allows to specify a label delimiter: the part of
+each line before that character will appear during the selection, and
+the part after that character will be returned.
-The Up and Down cursor keys move the selected line accordingly, and
-PageUp and PageDown move by ten lines. The Home and End key move to
-the top and the bottom of the list respectively. The return key
-selects the current line and exits.
+.SH "KEYS"
-You can cancel the selection either by interrupting the command with
-^C or by typing ^G.
+Keys corresponding to ASCII codes between " " and "~" add a character
+to the pattern string. The Backspace key, "^H" and "^?" delete the
+character immediately on the left of the cursor, while the Delete key
+and "^D" delete the character at cursor location.
+
+The Left and Right cursor keys move the editing cursor
+accordingly. The Up and Down cursor keys move the selected line one
+entry at a time, and PageUp and PageDown move it by ten entries. The
+Home and End key move to the top and the bottom of the list
+respectively. The return key selects the current line and exits.
+
+The keys "^A", "^E", "^U", and "^K" do somehow what they do in
+readline, and you can exit selector without doing anything by either
+interrupting the command with "^C" or by typing "^G" or the Escape
+key.
+
+The key "^R" switches between the multi-substring and the regexp
+selection mode, and "^I" between the case-sensitive and
+case-insensitive modes.

-.SH "EXAMPLES"
+.SH "EXAMPLE"
To use selector to search into your bash history, you can use
-.B selector -i -b -v -f <(history)
+.B selector -q -b -i -d -v -w -l ${HISTSIZE} <(history)
+
+.SH "KEYBINDING IN BASH"
+
+You can associate selector to a single key in bash by using the
+command 'bind' in your bash initialization file. For instance, to
+associate it to M-r (that is, the "Alt" and "r" key pressed together),
+just add something like
+
+bind '"\\C-[r":"\\C-a\\C-kselector -q -b -i -d -v -w -l ${HISTSIZE} <(history)\\C-m"'
+
+in your ~/.bashrc.
+
+Note that depending on the configuration of your system, the sequence
+associated to the M-r key, which is here "C-[r", may differ. To figure
+it out, simply press C-q followed by M-r in the console.
+
+The control character "C-a" puts the cursor to the mostleft location,
+"C-k" erases the current content of the readline buffer, and "C-m"
+simulates the enter key.
.SH "BUGS"
-Probably many.
+There are modeline display problems if the pattern is too long. This
+program does not handle multibyte characters.
