I will add to the latest chain of messages with key binding problems after last update.
I was constantly using cmd + / for commenting/uncommenting in code.
However, on Czech Mac keyboard, / is under shift on the same key as "ú" and "[", so I had to use cmd-shift-ú.
Now, it just jumps into help menu for some reason.
I would change the key binding in System Preferences - however, I can't find toggling comments in any menu!
This is very frustrating, since I love the commenting/uncommenting feature and I can't find any way to use it. And I guess all Czech users have it the same.
(the czech layout on PCs is here - http://en.wikipedia.org/wiki/File:Keyboard_layout_Czech.svg - but as always, macs have it a bit different. the ú-/-[ key is next to P.)
