Locator eats shortcuts meant for editor

1. Open a file and place the cursor in it.
2. Press Ctrl+K.
   You're now using the Locator.
3. Type "t ab" and press Enter.
   This opens the "About Qt Creator" dialog.
4. Press Escape.
   The dialog closes.
5. Press Ctrl+W.
   Nothing happens.

Ctrl+W should close the current editor. In this case this would be the editor opened in step 1.
The point of the Locator is to make Creator usable with the keyboard. That experience breaks with this bug.
