Karabiner-elements: Adjust Natural Scroll Direction for External Mouse Only

[nfarrar]

This is circumstantially related to #792

In OSX, under System Preferences -> Trackpad you have an option to enable or disable the "Scroll direction: Natural" setting. When using the trackpad, I like this to be enabled, however when using an external mouse, I like this disabled. OSX does not provide the capability to do set this for specific devices, so I manually switch this depending on how/where I'm using my MacBook.

Does Karabiner have the capability to detect whether the trackpad or external mouse is currently being used and adjust accordingly?

This used to be a feature in Karabiner but is not yet implemented in Karabiner-Elements.

For now, if you're also using BetterTouchTool, the dev has recently implemented this feature (under Advanced Settings -> Mouse -> General), or you can use https://pilotmoon.com/scrollreverser/.

A perfect OS wide solution was discussed in 2015 https://discussions.apple.com/thread/6931667, to bad it's abondoned.

Karabiner was suggested to me for this very feature. Presumably, Karabiner isn't compatible with Catilina? That's disappointing, since this was the primary reason I was seeking out the software

@EasyDanger I downloaded BetterTouchTool and got it to work! I had also just downloaded Karabiner for this purpose and was disappointed. The app is compatible with Catalina but it does not have this feature in that version. Scroll Reverser is incompatible with Catalina as shown on their site:

As mentioned above, in BetterTouchTool, the dev has recently implemented this feature (under Advanced Settings -> Normal Mouse -> General). In your normal System Settings for Trackpad, keep it checked as "Natural", then check this reversal box in BTT and you should be good to go. I'm using a Bluetooth non-Apple mouse, hence Normal Mouse, otherwise I think there's an Apple Mouse setting.

FYI, Karabiner Elements (KEY) wasn't a total disappointment for me. It gave me the option of mapping my unused caps lock key to my more frequently used control or option keys, so that was nice. It has some other nifty features if you're unsatisfied with the existing configurable options.

I'm sure I'll find other uses for Karabiner. The button layout on my external keyboard is literally unusable in its default state, so I've already found some success by remapping several keys.

I found out the hard way that ScrollReverser isn't compatible with Catalina. Reading is fundamental. >.>

For those coming from google, you can already do this natively with settings->keyboard->modifier keys

I'm currently using scroll reverser on Catalina, the dev does say it's inconsistent but you need to manually add an additional permission

For Scroll Reverser to work you will need to have it enabled in both the Accessibility and Input Monitoring lists under System preferences → Security & Privacy → Privacy

I might need to checkout BetterTouchTool.

One semi-related thing, I keep seeing karabiner settings for remapping home/end keys to command+right and command+left. I found better results with remapping them to control+a and control+e respectively. The shift modifications I've left using command+arrow functionality.
