Add UNDO (and REDO) for expression text box
Brought to you by:

When you are trying to find a good regular expression, then it would be good if you could undo the changes in the text box. Currently you need to CTRL-A, CTRL-C, then change, focus text field, then CTRL-A and CTRL-V. If the text field would support UNDO it would be more natural in the Eclipse environment.
