Enable Commits InPlace Editing

In order to maintain the standard F2 for in-place renaming, I change the command-line shortcut to F3.
This in-place editing is different than Windows Explorer in-place editing in regards to double-click. In my change, editing starts immediately and doesn't wait to see if this is a double-click. I think this is better, as double-click is less used. Double-click can still be done on the node icon.
