Spacebar is not a shortcut anymore in CC 2014 it seems. Trying to set it as one.. an error displays: "You can only use A-Z for tool shortcuts"
How can I get that shortcut back?
It works for me. Press and hold the spacebar and the hand appears, then I can pan the image around. Nothing special had to be set, it works that way right out of the chute.
What does it do for you, exactly?
Also, please describe what system you have (Mac or PC, specifications). Ideally, Help - System Info in Photoshop, copy, and paste that info into a post here.
