Have a 'new to me' Lenovo x61tablet with a pen input. In Photoshop, is ctrl/alt/z only available from the edit menu, or is there an icon I'm overlooking? Can I program the direction pad for this function if needed?
Photoshop CC 2015 has a modifier panel that can help tablet users using a pen (or finger) input. Menus in Photoshop are customizable, so you could add a key shortcut to anything. And you can program the tablet driver to issue key commands.
