Start typing in keywords to list out entries. Press Enter to select an entry. The selected entry will be run through a shell.
To set spmenu options, you pass arguments to 'spmenu_run' directly. See 'spmenu --help' for a list of valid arguments.
To configure spmenu, you may also copy ${DESTDIR}${PREFIX}/share/spmenu/example.Xresources to $CONFDIR/spmenu/spmenurc and edit that.

- Type in '?' to show this help screen at any time.
- If the entry selected starts with 'www', it will instead be treated as a link and spawned in a web browser (\$BROWSER)
- If the entry selected starts with 'magnet', it will instead be treated as a magnet link and spawned in a torrent client (\$TORRENT)

$(printf '\033[0;31m')Note: This may also be displayed if you deleted your spmenu configuration directory.
