5/22 Smart Scroll 4.6.5: (M1 and Intel Macs) Crash fix, inertia after scrolling.

Smart Scroll 4 is a free upgrade for users who have already upgraded to 3.9. If you didn't upgrade to 3.9, you can upgrade to 4.x instead, for the same $7.
Smart Scroll 3 is still available, up to OS X Yosemite: Smart Scroll 3.9.22.

Smart Scroll makes scrolling smoother, faster and more comfortable:

Improves even the latest trackpads and mice. Other features include independent reversal of trackpad and mouse, trackpad and scroll wheel acceleration, and more.


Scroll Wheel+ Multi-Touch+ Scroll Wheel+ Multi Touch+

Amazingly smoother scrolling, much easier for reading than the built-in scrolling.

Scroll Wheel+ works with any scroll wheel mouse that Apple's Mouse preference pane can see, while Multi-Touch+ enhances trackpads and Magic Mouse. So you can choose separate settings for trackpad and scroll wheel, such as different speeds and inertia.

If you're using a scroll wheel, try this, it's how scrolling should be, you won't want to go back!

Hover Scroll Hover Scroll

Simply point the cursor to the top or bottom edge of a scrolling pane to scroll. Move closer to the edge to scroll faster.

To show the zones where Hover Scroll responds, hold the option/alt key and move the cursor near the bottom of the window (or top). You can drag these zones to position them in each application.

Use the Left/Right arrow keys to adjust speed on the fly. Scroll back with the Up arrow key, and use the Down arrow key to skip forward.

If needed, click or hit any key to stop scrolling while the cursor is in the hover zone near the edge. To scroll again, move the cursor out of the zone and back in again.

You can choose how far from the edge scrolling occurs, and you can set the highest speed to scroll at (i.e. when the cursor is closest to the edge).

These settings can be customized for each application.

Auto Scroll Auto Scroll

Read more comfortably, hands-free! The page scrolls automatically.

Press your chosen hot key then sit back and relax while the page under your cursor scrolls automatically to keep up with your reading. If you need to adjust the speed, or scroll back up, or skip forward, use the arrow keys as with Hover Scroll (see above), or you can also move the cursor up/down.

Auto Scroll can also be started with smartscroll://autoscroll and autoscrollUp

Grab Scroll Grab Scroll

Graphics tablet and mouse users, Grab Scroll lets you move window contents in a manner similar to the hand tool feature common in graphics programs, except:

Grab Scroll works with any kind of mouse, pen & tablet, trackpad, trackball... With a 2-button mouse, set it to use the secondary button and you can then click-and-drag to Grab Scroll, or click without moving the mouse to get the usual "right-click" menu.

With 3 buttons, you can click-and-drag with the middle button to Grab Scroll, or click to open links in a new tab or to perform any other action that does not involve dragging.

You can also use a hot key to trigger Grab Scroll. With a Wacom pen, set the pen button you want to use for Grab Scroll to generate a key combination, then set that same key combination as the hot key trigger for Grab Scroll.

Grab Scroll can also be started with smartscroll://grabscroll, and stopped with smartscroll://stop

Universal Scroll Keys Scroll Keys

Scroll Keys let you scroll from the keyboard in all applications, with only one set of keys. This gives you consistent, dependable scrolling everywhere, without having to remember which application uses which keys and without having to reach for the mouse.

Scroll Keys use a kind of keyboard shortcut which doesn't involve hitting letter keys, thus avoiding conflicts with existing key combinations. You hold one of these keys and tap one of the others:

modifier keys

Here's how to scroll down :

Hold down the control key key, then tap the command key key once.

To scroll another line, just tapŒ˜ Command again (while still holding downŒƒ Control ). After scrolling once, you can keep both keys down to keep scrolling. If a window has two or more scrollable panes, it is the one under the mouse pointer that scrolls.

Because these keys are conveniently located in the corner of the keyboard (both corner on some keyboards), you can scroll without having to even glance at the keys.

You can choose your own preferred combinations of these keys. Scroll Keys also feature an adjustable scrolling speed, with optional progressive acceleration, so that you can easily scroll multiple pages simply by holding down a key.

Scroll Keys can also be triggered with smartscroll://downOnce, upOnce, leftOnce, rightOnce

Vector Scroll Vector Scroll

Popular with Windows and Firefox users, now available for all Mac apps!

Click and then simply move the cursor in the direction you want to scroll. The farther you move from the anchor point the faster the page scrolls. It's also known as "rubber-banding".

You can use Vector Scroll to scroll hands-free, nudging the cursor when you want to adjust the speed.

To stop, click or hit any key.

Vector Scroll can also be started with smartscroll://vectorscroll, and stopped with smartscroll://stop
