I'm on a Macbook Pro, working quite a lot in Google Sheets. So I've deactivated the F-keys (so there's no F2). But I can't find a shortcut for editting a cell with text in it, in Google Sheets. If it's an empty cell, yeah - then I can just start typing. But if I want to edit a cell with stuff in it, then I can't seem to find it. I've tried these:CMD-EnterCTRL-EnterCMD-uCTRL-uCMD-eCTRL-eFN-F2 is not an option.I don't want to use the mouse (double-click on cell). It's so clumbsy and slow.
