i want to remap my up arrow to prev edit and down arrow to next edit similar to FCP7 shortcut, however, when i edit the CS5.5. default shortcut key layout nothing seems to change on the macbookpro? I could use the FCP7 layout but i want to try and learn the CS5.5 shortcut keys. There is not Page up or Page down equivalent on the Mac keyboard. I've discovered that fn+left arrow=sequence start and fn+right arrow=sequence end. I am wondering if someone has uncovered this holy grail or could give me some pointers.
Try Fn+Up Arrow and Fn+Down Arrow.
