Cannot use the 'tab' key to move to the next cell. One must click into it.
If you are unaware of this, press Tab, and start typing, it looks like nothing happens.
Click Update. Go back into the page.
The cell where the cursor last was prior to the 'tab' action is all mucked up (contains what you thought you typed after the 'tab' action, but it didn't show).
Is this a bug, or annoying function?
