- Added Ctrl+A and Ctrl+E for moving around the edit bar a.la. Emacs
- Added the "yank" and "paste" command to copy and paste a single cell value. These are mapped to "y" and "p".
- Modified the edit bar so that entering commands is the only case where typing backspace on an empty edit bar will cancel out of edit mode
This runs a search and replace over the entire model. This is just
temporary at the moment in order to get something working.
Also added hitting backspace on an empty entrybox to cancel it.
