[Tex/LaTex] LYX: how to mark power set


This is my first time here and I did my best to figure out if such a question is in place here. If I missed something I apologize.

My questions is how can I mark a power set in the lyx document editor?

For example: I'd like to write P(A) when A represents a set, but in the special marking normally used for the power set. I assume there should be a '\shortcut' kind of thing, but I'm new to lyx and can't find one.

Thanks in advance…
