Hi Carl! I just found a keyboard shortcut that isn't common but may be of some use to a few readers. I use a non-standard keyboard with my computer. It's a small bluetooth keyboard and, like many in this class, it is missing the home, end, page up, and page down keys. Keys that are frequently used in both TS3 & TS4. I've actually been looking to buy a small, quality, BT replacement keyboard that includes those keys. But today, by pure happenstance, I made a discovery! Those four missing keys aren't missing at all, they're just unmarked! When you hold down the 'FN' (function) key while pressing the arrow keys they will perform the required functions. Specifically, FN + Left arrow = HOME, FN + Right arrow = END, FN + Up arrow = PAGE UP, and FN + Down arrow = PAGE DOWN. Like I said, its rather obscure but could be useful.
If you decide it's worth using you can show my name as: Trich aka 1Saved_Diva . Thanks for letting me share and keep up all the great work!
