Grip functions as a full-featured CD player, as can be seen in
Figure 1. Tracks can be selected by clicking on
them with the left mouse button. Double-clicking will select the track,
and begin playing it.
Underneath the "LCD" display is a panel of buttons that allow
you to control CD playing in Grip. These buttons function as
follows:

Play/Pause — Causes the selected track
to play if it is stopped or paused. If a track is currently
playing, it will go into pause mode.
Rewind — While this button is held
down, Grip will move backward in the currently playing track.

FastForward — While this button is
held down, Grip will more forward in the currently playing
track.
Previous track — If a track is
currently playing near the beginning of a track, this will
rewind to the beginning. Otherwise, it will skip to the previous
track.

Next track — This will skip to the next
track.
Track Mode — This brings up the track
mode interface, described in the section called Track Mode Selector.

Stop — Stops track playback.
Eject — Opens or closes the cdrom
tray.
Volume — Toggles display of the
volume control slider interface.
Track Edit — This brings up the track
editing interface described in ...
DiscDB — This initiates lookup of the
CD over the network, or aborts a disc lookup currently in
progress.
Min/Max — Toggles between the "full"
and "cd-only" (shown in Figure 2) display
modes.

Quit — Exits Grip.
