Keyboard shortcuts in debugging windows

[getvega]

First of all, many thanks for bringing us this wonderful devtool.

Would that be possible to bring some shortcuts specific to xdebug windows (like SublimeGit)?

Some useful ones I would think of :

• XDebug Watch:
  • backspace to delete the selected expression
  • enter to edit the selected expression
• XDebug Breakpoint:
  • backspace to delete the selected breakpoint
  • enter to edit or add a break condition
