Weirdly the Fn key doesn't change how the F row registers... I wonder if I can do something about that.

11 is what I use on macOS, but I feel like my eyes are working harder here.
2021-02-07Fully configure and rebind cwmJune McEnroe
This is sort of a mix of trying to emulate macOS somewhat for my muscle memory and just rebinding some of the cwm defaults to use 4- rather than M-.

2021-02-06Add initial OpenBSD X configurationJune McEnroe
cwm still needs a lot more rebinding, and I need to actually look at its other options. xterm definitely still needs some configuration, but I at least managed to get it to use a decent looking font. Very happy that OpenBSD includes Luxi Mono, which is what my usual font, Go Mono, is based on anyway. Still missing is xmodmap and such.
