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)
|
|
- If the entry selected starts with '?' followed by a valid command, it will be opened as a man page in spmenu.
|
|
- If the entry starts with '#' followed by a valid command, it will be opened in the defined terminal emulator.
|
