All About DoubleScroll
DoubleScroll is a combination Extension/Control Panel which alters the way your Macintosh scroll bars look and act. Basically it puts a double arrow on each end of your scrollbars, allowing you to scroll in both directions without having to mouse from one end to the screen to the other to scroll back and forth. It works in both System 6 and 7, but it is really designed to take advantage of the color scheme of the System 7 interface. In fact, this text block has a DoubleScroll scroll bar on the right, whether or not DoubleScroll is currently loaded. Try it out!

Though the idea of double-arrowed scroll bars is not new, I decided to give it a new twist with System 7 and make them look identical to the standard scroll bars when displaying in color as well as black and white. They look like genuine Apple-issued scroll bars. So they’ll blend right in with the rest of your interface without standing out and looking odd. If you change the color scheme of the windows with the “Color” Control Panel in System 7, they’ll change with the rest of your decor! These are scroll bars the way nature intended (and Apple should have supplied). When space starts to get tight, you will notice that the scroll bars will lose their double nature and revert to the normal way of doing business, just to give the thumb (the little box) a little breathing space.

DoubleScroll was tested on a Mac II with a PowerCache accelerator under System 6, and also in both 24 and 32 bit addressing mode under System 7. It has also been tested on a PowerBook 140 and a Mac SE for good measure. 

NOTE:
Because DoubleScroll has two arrows at each end of the scroll bar, this may cause problems when using it with macro recorders which simulate page up/page down clicks in the scroll bar. Instead of clicking page down, it may decide to scroll up because the up arrow is where there is normally gray fill! Don’t you hate when that happens! Since I do not have any macro programs, I can’t be sure of the results. Any feedback you could give me would be appreciated.

DoubleScroll also supports balloon help under System 7, so if you feel like playing around, knock yourself out!

Installing DoubleScroll
For System 6 users, drag DoubleScroll into your System Folder. For System 7 users, DoubleScroll should be placed in your Control Panels folder, located in your System Folder. To do this the easy way, simply drag DoubleScroll to your System Folder. A dialog box will come up asking you if you want to put it in the Control Panels folder. Just click OK and the system will put it in the right place.

Once in its new home, you need to personalize DoubleScroll. If you do not personalize it, you won’t be able to work the control panel, and the DoubleScroll will not load at startup. If your running System 6, select the Control Panel from the Apple menu and find DoubleScroll in the list of icons and click it. In System 7, open the Control Panels folder and double-click the icon. DoubleScroll will come up and ask you to personalize it with your name or company name. After personalizing it, DoubleScroll is all set to run. Just close the control panel and restart. It’s that simple!

NOTE: Holding down the Shift key during startup will stop DoubleScroll from loading.

Controlling the Control Panel
DoubleScroll provides three options in it’s control panel:

Use DoubleScroll:  Click this button to use DoubleScroll’s scroll bars the next time you restart your computer.

Don’t use DoubleScroll: Click this button if you don’t want to use DoubleScroll’s scroll bars the next time you restart.

Show DoubleScroll’s Icon at Startup: If this button is checked, DoubleScroll will display its icon when your computer is booting. If it is unchecked, the icon will not be displayed.

Registering DoubleScroll
DoubleScroll is not free. You are allowed to use the product for 15 days, after which you should either throw it in the trash can (bad choice) or register it (good choice). If you do not register, a message will come up each time your computer starts up stating that the 15 day trial period is over and to please register your copy.

To register your copy, first you need to tell me that you have it. Click the Register... button in the control panel. This will bring up a dialog box giving the address to send your payment of $7. After I receive your payment, I will immediately send your registration code, which will prevent the reminder messages from appearing. Just enter it into the spot in the Register dialog box and you’ll be cookin’!
