Jonathan: I think maybe you've gotten your commands mixed up here, but you're close. The command you want What you really want here is page up or page down, depending. The Control Page Down or Control Page up moves by marks.

In other words, when I press the control+pagedown or control+page-up, I would like for Studio to navigate one hour backwards or ahead depending on the keystroke. I tried to set the navigation setting to 1 hour, but it wouldn't allow me to do this. I could use the "goto time" command, however, I have to enter an hour every time. How can I navigate the file in hour incruments with a keystroke? Jonathan
