Scroll Switcher is a small utility designed to allow the user to quickly and easily change the scroll arrow configurations in Mac OS X.
DoubleBoth
This setting is not normally available in the Finder. The full set of scroll arrows are placed together at both ends of each scroll bar. To do the same using the Terminal, you would type:
defaults write -g AppleScrollBarVariant -string DoubleBoth
DoubleMax
This is the default setting in Mac OS X. The scroll arrows are placed together at the bottom of the vertical scroll bar and at the right of the horizontal scroll bar. To do the same using the Terminal, you would type:
defaults write -g AppleScrollBarVariant -string DoubleMax
DoubleMin
The scroll arrows are placed together at the top of the vertical scroll bar and at the left of the horizontal scroll bar. To do the same using the Terminal, you would type:
defaults write -g AppleScrollBarVariant -string DoubleMin
Single
In this mode, the scroll arrows are placed separately at the ends of each scroll bar. To do the same using the Terminal, you would type:
defaults write -g AppleScrollBarVariant -string Single
Once a setting is chosen, Scroll Switcher directs the Finder to quit and relaunch to apply the new setting. To restart the Finder using the Terminal, you would type:
killall Finder
