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. -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 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.
