Is there a keyboard short cut to edit a cell in Numbers? Back when I used Excel you could easily do all the navigation and editing on a spreadsheet with the keyboard. I could navigate around with the arrow keys and hit F2 to edit a cell and start typing.

In Numbers '09 I can navigate easily using the arrows then start typing to overwrite the contents of a cell. But I can't figure out how to navigate to a cell and then edit its contents without clicking on the cell with the mouse[1]. 

Is there an easy way to do this without the mouse?



1 -  Okay, so I did figure out one way (&#x2318;+C, space, backspace, &#x2318;+V) but it's such a hack that the mouse starts looking better.
(⌥OptionEnter↩).

Or just return if you've unchecked Return key moves to next cell in the inspector:
