Scrolling Tip For Mac OS X

Here's two cool tricks I learned about today. The scrollbar on Mac OS X has two arrows, like any other scrollbar. You can opt to have these arrows next to each other on the scrollbar, and when you do, you can hold down on one to start a scroll, and while holding down, move to the other one, and the scroll will instantly change direction. Not earth shattering, but useful to know. One thing though, these arrows are always at the bottom. This can be changed however. You can open a terminal, and type the following command, and all windows with scrollbars that are opened from this point forward will have the set of arrows at both ends of the scrollbar. Rather nifty.
