I’m used to FinalCutPro. There don’t seem to be keystrokes available to mark the beginning and the ending of a clip. How can you drag if you don’t have a precise clip marker on either side?
Audacity doesn’t have Mark-In and Mark-Out. This drives the video people nuts.
We do have labels. Note that if you do use labels, you must link the show track with the label track, or at the first edit, all the points and times will be wrong.
Audacity has clips.
As Koz points out you can’t Mark-in and Mark-out on the fly, but you can precisely mark in and out point (thus creating a clip) by listening, zooming in and identifying the points.
