How to access Gameplay Developer Tools (GDT) from within the game on non-US keyboard??

To access GDT one can simply start the simulation mode within the edtior and click on an AI-controlled actor. Additionally from a running game (instead of simulation) one can also focus an AI-controlled actor and hit the ’ (apostrophe) key.

However, the latter does not work for me. That is maybe the case because I am working with a German keyboard, on which we need to hit SHIFT+’ in order to access the apostrophe character.

Has anybody of you experienced the same and knows a solution to this?
