What is the purpose of the Control+Shift+O keyboard shortcut?

The keyboard shortcut Control+Shift+O is used to remove the Out Point of a clip in the timeline. This functionality is particularly useful when you want to adjust the duration of a clip without having to start a new selection. By removing the Out Point, you allow editing software to treat the clip as playing to its full extent from the In Point to the end of the media.

Understanding this shortcut can streamline the editing process, making it smoother and more efficient, especially when working with multiple clips and trying to create seamless transitions. It's a vital feature for editors who frequently engage in precise cutting and trimming of clips on the timeline.

The other choices represent different actions that do not align with the primary function of this shortcut. For instance, opening the export window, setting an In Point, or isolating audio tracks each have their distinct keyboard shortcuts and do not correlate with Control+Shift+O. This precise knowledge of keyboard shortcuts can significantly enhance workflow capabilities in editing software.
