Thanks for that awesome table selection, makes copying stuff out of PDF tables really really easy and straight forward, However:

Exiting the table selection mode is not really intuitive. The info bar gives a hint to press Escape but I think when you click outside the selected area, it should cancel the selection. Especially when you moved to another page you find yourself unable to select something as there is a selection somewhere else going on. Usually you can do a new selection when starting to drag outside the selected area. This does not work with the table selection tool.

Reproducible: Always

Steps to Reproduce:
1. Use table selection tool (Ctrl+5)
2. Select something
3. Try to select something else or desperately to exit the selection mode ;)
Actual Results:  
You have to press Esc to leave the selection mode in order to start a new selection

Expected Results:  
The selection exits when you click outside the selection, or a new selection starts when starting to drag outside the selection.
