Seeing as it wasn't mentioned, there's a Ukelele[0] app for making keyboard layouts for macOS. After installing, switching layouts is as easy as tapping 'fn' by itself or using the keyboard menu icon. [0] https://software.sil.org/ukelele/. - Source: Hacker News / 12 days ago

I also use a QWERTY keyboard and I use a custom keyboard layout that maps alt-a to ä, alt-u to ü, alt-o to ö, alt-s to ß (plus the same for uppercase for the first 3). That works well for me without the need to post-process. On macOS it's relatively easy to create using a tool called Ukulele (https://software.sil.org/ukelele/). You can also download my layout here: https://alex.kirk.at/USUmlaut.keylayout. - Source: Hacker News / 6 months ago

I’ve always set up a custom keyboard for exactly that! () on their own keys, [] on shift and {} above 0 and 9. It always struck me as the most natural alignment for prose and programming. Thankfully between Ukelele [0] and MSKLC [1] it’s pleasantly simple to do [0] for macOS: https://software.sil.org/ukelele/. - Source: Hacker News / 9 months ago

Hey everyone, I have created a custom layout with Ukelele and everything works great except that the icon for my custom layout is narrower for some reason, in comparison to the default layouts. I tried everything, but I can't make it normal size. Source: 10 months ago

They could have used the SIL Open Font License instead. People in the open source world are often already familiar with it, and resources like tl;dr Legal are available for it. Their EULA is, in fact almost exactly the SIL Open Font License, but someone decided minor changes in wording were more valuable than standardization. https://scripts.sil.org/cms/scripts/page.php?item_id=OFL_web... - Source: Hacker News / almost 2 years ago

I've used Smooze [1] in the past. It has a ton of features, but I really just need it for turning off mouse acceleration and making the scroll wheel usable. Glad to see an open source option. [1] https://smooze.co/. - Source: Hacker News / 12 months ago

Smooze is the best app I have found to make using mac with a non-mac mouse even remotely usable. Really wish Apple would care a little more about mouse support. Source: about 1 year ago

Mac unfortunately isn’t the best at supporting third party mice and their additional buttons, for your specific case, the only app that I know of that offers a similar option would be smooze. Source: about 1 year ago

What mouse are you using? - SteerMouse is a nice app that can remap buttons. - Smooze I think also had some options for buttons. Source: over 1 year ago

Hey guys, I've recently added some trackball improvements to the grab scroll feature in Smooze Pro and I'd love to get some avid trackball users input on this. Source: over 1 year ago
