It's not regular typing. It's primarily using the f-keys and numbers. Particularly for functions in my IDE.

Most of the time I'm using an external monitor and keyboard, so get very little practice on the built in one except when it's in less than ideal situations like flying.

When I get my next laptop, I'll be keeping Linux capabilities in mind. But that's years away. I'm not even sure where to start with reverse engineering the hardware, and also don't see myself spending months of my free time to make it work. I don't have that much free time and there are too many other things I'd like to be using that time for.
