VideoTrack's F5 advice is spot on! However, be aware that any changes you make in the F5 window stay in place until you make another change.

For example, let's say you want to mute the bass for four bars starting at bar 5. While the cursor block is in bar 5 press F5 on the keyboard to open the F5 window. Select the drop down menu for the bass track and change the selection to -MUTE-. Advance the cursor block to bar 9, press F5 to open the F5 window and select the drop down menu for the bass track and change the selection to -return to normal-. The bass track will mute at bar 5 during playback and will remain muted for bars 6, 7 and 8 then un-mute at bar 9.
