What is the keyboard shortcut to trim the end of a clip in the timeline a frame at a time?

I'm not aware of any keyboard shortcut for snipping off one frame at a time from a clip.

If you need to do that often enough, methods of creating "keyboard macros" are available for Windows.  I googled "keyboard macros" and found several links.

But what keystrokes would one employ to do a one frame trim? At one time I had it set up on my Shuttlepro, but I need to re-set and have forgotten the keystrokes.
