What default function is associated with the space bar while in trim mode?

In trim mode within AVID Media Composer, the space bar is associated with the function that toggles play and pause, but it plays the selected clips in a continuous loop. This is particularly useful during the trimming process, as it allows editors to review transitions seamlessly and make more informed adjustments. The looping feature gives a perspective of how the edited sequence flows and ensures that the editor can effectively gauge the timing and pacing of the transitions being altered. This immediate playback feedback while trimming aids in making precise edits and enhances overall efficiency in the editing workflow.
