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.
