In-Depth Information
(open Finder, select the Applications list, and then in the list of applications
double-click Terminal within the UTILITIES folder), and type the following:
DEFAULTS WRITE -G APPLEMOMENTUMSCROLLSUPPORTED -BOOL FALSE
Log out and back in again for the change to take effect.
To reenable inertia scrolling, either repeat the previous steps to activate it
within System Preferences or—if you've disabled it using the secret command
described earlier—open a Terminal window and type the following, logging
out and back in again for the change to take effect:
DEFAULTS DELETE -G APPLEMOMENTUMSCROLLSUPPORTED
Scrolling Horizontally Using PC Mice
Newer Apple mice have special scrollballs or small trackpads that allow both
vertical and horizontal scrolling. Most standard PC mice simply have a scroll
wheel that allows only vertical scrolling. However, to scroll horizontally using
any mouse, just hold down SHIFT while turning the wheel.
Jumping to a New Location Using the Scrollbars
You can scroll up or down a page in the document or website you're viewing
by clicking the area above or below the scroller in the scrollbar. Usually this
will cause the application to scroll page by page. Sometimes, however, you
might want to simply jump to a new location in the document without having
to scroll one page at a time. To do so, move the cursor to where you want to
jump on the scrollbar, hold down OPTION , and click the mouse button. This
will cause the slider to jump instantly to that spot.
This can be very useful if you want to jump to the beginning or end of a doc-
ument—just hold down OPTION and click at the top or bottom of the scrollbar
range.
Slowing Down Scrolling
Holding down OPTION while you click and drag the scroller (the little bar that
shows your position within a document in the scrollbar) will slow down
scrolling. It's best shown in practice, so give it a try—grab the scroller in any
open window displaying a large file, and then hold OPTION and drag. You see
that as well as slowing down, scrolling becomes more fluid, making it easier
to read the window contents as they scroll by.
