Enable the tab and enter keys to go to next unlocked cell, currently it will go to next cell even if locked for editing and show a warning.
This is incredibly annoying! I lock cells to make forms that I can edit on the fly and having an error message tell me every time the cell is locked is incredibly frustrating. I know it's locked, I'm the one who locked it. Tab/Enter should act just like the desktop version. Any other way is nonsensical.
