+Description: A command line for dynamic string-matching.
+ This is a command line 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 with matching content. 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.
