Canon’s Digital Photo Professional has a few unpublished shortcuts, I’ve recently found out, which are very handy. I’ll list a few below.

In the quick check tool hit the SPACE key to switch between the fit to screen and the 50% views. Excellent, no need to use the mouse! By the way double-clicking the photo will also do this, in case you insist on using the mouse, but would rather not move over to the button area each time or preview the photo in full screen mode.

Also, in the quick check tool you can rate photos by repeatedly hitting the V key. It will cycle through rating 1, 2, 3, and clear.

If you select photos you’re about to ‘quick-check’, use the left and right arrow key to jump from one photo to the next.

I’m still desperately looking for a shortcut to the view before and after in the edit mode. I’ll update this blog entry as I find new useful undocumented shortcuts.

Update on Mac OS X: DPP ver. 2.2.2.3 does not support such shortcuts and one has to use the mouse. Moving in quick check tool is possible by using the arrow keys while holding the Option key–so one needs two hands (!). Sorry to find that although DPP 2.2 for Mac OS X is a fast universal binary, it still has shortcomings compared to the Windows version.
