@Andreas_Hegenberg I'm trying to figure out what the AD "currently pressed keyboard key" does.
I thought if "space" is pressed and held plus another key (letter) is pressed then that may trigger something. But apparently not. 
Can you please explain me briefly what it really does? Thanks!
what's 'AD"? 
Advanced Conditions 
Ah, ok, right now I don't see what I could use that for.
But wouldn't that be a realizable possibility? If "currently pressed keyboard key" is Space and I press another key, then something is triggered? 
wouldn't it be just a key sequence then?
The conditions never trigger something on their own, they always only further specify an existing trigger.
You're right. It would be the same as the sequence below. It only triggers if "a" is pressed and held while "l" is pressed. Sorry, my thinking error 
It happens to me that the currently pressed keyboard key has nothing to show whenever I press the a-z and number key. It only shows when I press the key control command or shift, what can I do for it?
Most likely secure input mode is active on your machine, or BTT doesn't have the necessary permissions to monitor keyboard input.
If secure input is active BTT will show it when clicking the menubar icon
Do key sequences work in general?
The key sequences works fine. Somethings weird is that whenever I test the key in recording the key sequences it works, and then I quit to check for the currently pressed keyboard key element, it does show the number. However, when I save change for that once and then have a double check, the number doesn't display again.
For the if conditioning setting, even I set the correct number and press it, it fails to recognize it.
Could you please have a look into this?
For further detail, I didn't see anything related to the secure input on the menubar icon and I have also try an apple script to detect if the secure input mode is open. The result tells that it wasn't open. Hope this can give you some clues.
