Photoshoplab lists the top 7 keyboard shortcuts in Photoshop to aid productivity.

To list a couple:

Ctrl + Alt + Z – Undo multiple times. I use this one all the time. Very useful.

Ctrl + 0 – Fit to window. Again, very useful and I use it all the time.

Spacebar – Hand/move tool. Wasn’t aware of this one.

There are a few that aren’t actually listed that I think should be, they are as follows:

B - Select pencil tool

G – Select paint bucket tool

T – Select text tool

P – Select pen tool

Infact if you hover your mouse over each tool button, you will see in brackets what the keyboard shortcut is for that tool.
