I have some issues using the shortcuts on Photoshop CC, I just installed the app in French, and some shortcuts aren't the same as in this page Raccourcis clavier par défaut dans Adobe Photoshop and either doesn't match with English shortcuts. My keyboard is azerty, I'm using Windows 10 in FRA keyboard ( azerty too )
as example to decrease/increase brush size it's not , and ; but : and !
and more examples..
I tried in English version it's even worse, in this case , ; : or ! dont work either
Due to new features being added, the keyboard shortcuts for some things were changed in the latest version of Photoshop. I think this might be what you are running in to. But remember, you can always change the shortcuts to whatever you want them to be. Just go to the Edit dropdown menu and click on Keyboard Shortcuts.
I've just come across this while searching for a similar problem with my French laptop with an AZERTY keyboard. On my main QWERTY PC I can change the position of a layer using Ctrl and the [ and ] bracket keys. This doesn't work on my French laptop. To get at the bracket keys on my laptop I have to hold down the AltGr key, so the key press for left square bracket is Ctrl + AltGr + [ . This gives the correct symbol in, say, Notepad, but PS doesn't recognise it . In addition if you go to the shortcuts menu and try to enter Ctrl + AltGr + [ what appears in the PS shortcut box is Ctrl + AltGr + ( . i.e you get the left round bracket, not the square one. So there appears to be some coding error in PS. I don't know if this is related to the way you access symbols on certain laptops or whether it's to do with the French keyboard layout. The only answer I found was to try to program the shortcut keys as I thought they should be then ignore what Adobe showed in he box.
