I use Photoshop on my Microsoft Surface in Tablet mode (With the keyboard flipped around). The way I employ hotkeys is that I have a USB tenkey and I map tools to the tenkey. The problem is that Photoshop will ONLY allow A-Z... I have no idea why that is... Could we open up the key mapping to anything on a tenkey? 1-0, /, *, -, + , . , BS, Enter, Num Lock. Thanks!
