Arrows hack for mountain lion?

There is a workaround, but it requires 3rd party software:

Download a utility capable of executing a scroll wheel simulation macro, triggered by a keyboard shortcut.

I'm using Keyboard Maestro which is an incredibly powerful tool in its own right.

I've created four global macros, each one simulating Scroll Wheel Up/Down/Left/Right.

The scrolling value can be set as low as 1 pixel ⚠ per keystroke. (I'm fine with 5…)

Each macro gets a global keyboard shortcut:

⌃⇧⌘↑

⌃⇧⌘↓

⌃⇧⌘←

⌃⇧⌘→

These modifiers are optional, but over the years I've developed the habit to use ⌃⇧⌘ strictly for global shortcuts active in all applications. This habit avoids possible conflicts with internal application shortcuts, because this modifier combination is rather uncommon.

Note that among others, Keyboard Maestro also supports Device Triggers instead of simple hot keys, which may also solve the issue for people with certain handicaps.

To get contiunous scrolling while holding the keys/device input down, make sure the trigger setting is "is down", not the default "is pressed".

Also note that the pointer must be over the affected window – same as if you'd be using a real scroll wheel – for the shortcuts to work.

It works in all application windows which support scroll wheel input, including text forms like this one I'm posting this reply.

Hope that helps

For those who are unhappy with the current arrangement, send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

You might try this - haven't used it, so I don't know if it will work.

LionScrollBars

^^ It doesn't seem to me that it can add the arrows to a scroll bar.

Custom scroll bar settings per app is a neat idea though, and likely useful for some. But I for one want to see my scroll bars at any time, in every app. 😉

Then simply tick that option in System Preferences > General. No need for crapware to do this.

Pete, from what I seen in your earlier comments here and in other similar topics: you're still not getting the point, are you?

So why do you even bother to post the same non-constructive reply over and over again?

No offense, but I'm puzzled.

Yes, I'm aware of the "simply tick that option in System Preferences > General". It was one of the first things I did after I started my new MBP for the first time, thankyouverymuch.

But that's not the point here.
