esc - ctrl - b works for me, but alt - b does not work. Itβs right there in the emacs key card, so at first itβs strange, but I think the problem is that alt - b maps to the character (β«, not Γ in my case), so PyCharm does not see it as a key-modifier pair, just one character.
Switching to another card on the international keyboard will change which combinations work and which don't. I suggest sending a bug report to PyCharm as it can fix it, or, as an alternative, you have to redraw the keyboard somehow.
To answer another question, I donβt think there is a way to go to the corresponding bracket, or at least I never found it.
