Presently I have to go to Preferences to do the following.

For years I often want to have my Cursor not to be imprisoned and held hostage in the Selection that I've made. In such circumstances I'd like to know of a Keystroke I can quickly employ to have the Selection Collapse, without the need/requirement to click somewhere on the Timeline to Collapse the Selection. And then after this have the option to reinstate the Selection option once more.

Please tell me that there is a KS for this one?
