In the version 2016.2.6379, How do we send hotkey with null target set

How do we execute a send hot key activity with target set to null, cause some time is easier not to set a target, for example when you want to navigate use the keyboard in the right click menu,
when I try to indicate that element on screen, that option list will gone, and if I run with out a target, I will get this error:

What if the target’s title is dynamic, then the send hotkey wont work… how can i make send hotkey target to null,
the upgrade break my automation

fixed by using wild card
