the home/end keys on my logitech mx keyboard were driving me insane on my mac (11.5.2 big sur). for example, when editing a web-based textarea like this one, the home and end keys would act like page up and page down, making the whole webpage suddenly jolt up or down instead of just moving the inline cursor to the start or end of the line.

needless to say i really appreciate this snippet and the discussion! i followed the original instructions, accounted for the .json.erb file extension, and was able to reconfigure the keys in just a few minutes. thank you!

Note that (as of this writing) the docs folder has changed to be named public. So, you have to put pc-rules.json.erb in src/json and then the output will be in public/json/pc-rules.json.

Updated with the old version there too for historical purposes. I don't use a mac anymore at work so I can't test anything ;)

can anybody that already ran this post the resulting json please?

As of writing, this doesn't seem to work. Looks like the original repo lost its ability to compile ruby template files...
The workaround I ended up with is to simply use the "PC-Style Shortcuts" that can be imported into Karabiner from its own UI. They have all the shortcuts included in this gist.

thanks, this worked great for me too.
