Is there a quick shortcut or key to de-select the selection? If I want to move a corner then I need to not have anything selected so that I can pick it up. Sometimes my selection is off-screen when doing these things.
I would normally click on something then [shift]-click on it again to de-select it, but that seems like a work-around rather than an actual solution.
([esc] jumps out of the current group - sometimes it’s easier to use this and double click on the group again… but it’s easy to get lost.)
