Added a 'delete' action, with the keyboard.

Added a delete action from the keyboard, there's also
a possibility to add the same action from the menu, but
I frankly don't like much the idea. so, to delete a handler
now, you need to select it ( ctrl + click ) then press
the delete button. Multiple delection is also possible.
