You can convert between Time- and Object-based selections. Time selections are made with the Selector and Time Grabber tools. Object selections are made with the Object Grabber tool.
Converting to an Object selection is useful when you are working with large selections, especially across multiple tracks, and you want to remove certain clips from the selection.
Converting to a Time selection is useful if you want to select all clips between a noncontiguous Object selection.
To select clips that were partially selected, press Start (Windows) or Control (Mac) while double-clicking the Grabber icon.
When using the Object Grabber tool on tracks that belong to an Edit Group, clips in the other grouped tracks are selected if they fall within the range of the selected clip.
