Play Cut Preview C
Plays audio excluding the selection. The amount of audio that is played before and after the section is set by the Cut Preview setting in Playback Preferences.
The following two commands are there primarily so that you can know what their default shortcut keys are, and so you can change them in Shortcuts Preferences if required.
The menu commands are null and do nothing, only the shortcuts are designed to work.
See Scrubbing and Seeking for more details
Scrub Backwards U
While the U shortcut is held down, Audacity will scrub backwards.
Scrub Forwards I
While the I shortcut is held down, Audacity will scrub forwards.
|After pressing one of the two keys playback continues until the key is released. Playback starts from the cursor position or the start of a time selection if there is one. Scrubbing is not limited by any selection that may be present.
If one of the keyboard scrubbing keys is being held down, and the other keyboard scrubbing key is pressed scrubbing immediately changes direction, and does not stop when the original key is released.
