-\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
+\fBselector\fP is a command line utility for dynamic string
+selection. It reads the content of the specified files, and as the
+user types 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).
+
+This command was mainly designed as a way to search in the shell
+history, for which it is substantially more efficient than the
+standard readline ^R binding. With the -v option, it injects the
+selected line into the tty input buffer, hence allowing the user to
edit the line and execute it as a standard command.
-Selector is also a good tool to test regexps.
+Selector is also a handy tool to test regexps, or to display menus
+with many possible choices. For the latter, the -x option allows to
+specify a label delimiter: the part of each line before that character
+will appear during the selection, but only the part after that
+character will be returned.

+Note that because this is an interactive command, the standard input
+can not be used as one of the input files.

+.SH "KEY BINDINGS"
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 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.
+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 shortcuts "^A", "^E", "^U", and "^K" do somehow what they do in
+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 "^R" key switches between the standard multi-substring mode and
-the regexp mode, and "^I" between the case-sensitive and
+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 -d -i -b -v <(history)
+.B selector -q -b -i -d -v -w -l ${HISTSIZE} <(history)
-.SH "KEY-BINDING IN BASH"
+.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 -d -i -b -v <(history)\\C-m"'
+bind '"\\C-[r":"\\C-a\\C-kselector -q -b -i -d -v -w -l ${HISTSIZE} <(history)\\C-m"'
-in your ~/.bashrc.
+in your
+.IR ~/.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

-There are modeline display problems if the pattern is too long. If a
-line contains control characters, the returned line has been converted
-to printable characters.
+There are modeline display problems if the pattern is too long. This
+program does not handle multibyte characters.
