.SH "DESCRIPTION"
-.PP
-\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.
+\fBselector\fP is a command line utility for interactive real-time
+pattern matching. 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 efficiently in the
+shell history, for which it is substantially better 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 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.
-Selector is also a good tool to test regexps.
+Note that because this is an interactive command, the standard input
+can not be used as one of the input files.

-Keys corresponding to ASCII codes between ' ' and '~' add a character

+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.
+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 readline,
-and you can exit selector without doing anything by either
-interrupting the command with ^C or by typing ^G.
+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 case-insensitive
-modes.
+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"

+To use selector to search into your bash history
+
+.B selector -q -b -i -d -v -w -l ${HISTSIZE} <(history)
-.B selector -d -i -b -v <(history)
+To show a list of directories and insert a cd command to the selected
+one (using @ as a separator)
+
+.B selector -v -x @ <(find . -type d | awk \(aq{print $0\(dq@cd \(dq$0}\(aq)

+file contains ^A)
+
+.B selector -v -x ^A <(awk < something.txt \(aq{ print $0\(dq^A\(dqNR }\(aq)
+
+.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 \(aq\(dq\\C-[r\(dq:\(dq\\C-a\\C-kselector -q -b -i -d -v -w -l ${HISTSIZE} <(history)\\C-m\(dq\(aq
+
+in your
+.IR ~/.bashrc .
+
+This bindings uses the control character ^A to put the cursor to the
+mostleft location and ^K to erase the current content of the readline
+buffer, and it simulates the enter key with ^M.
+
+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.
.SH "BUGS"

-long.
