2. Select some word (double click or using keyboard).
3. Open context menu on selected word (right click or by using keyboard).
4. By selecting appropriate value from menu (delete or cut) remove word from editor.
5. Use Ctrl + Z combination to undo chagnes.

Actual result: Undo action was not called. Probably because was not added to stack.
