That's interesting - I never thought to do it this way. I tried it on a windows machine but couldn't reproduce the behavior; probably the keyboard saved a few bucks on the required wiring. Out of interest, can you send an evemu recording of a g0g0-like session, to see how it looks like on the evdev side? > a key.

Not formally, the simple single-key repeat behavior is well ingrained in both the XKB protocol and server-side implementation (i.e. there's a single repeat timer and a single repeatKey per device). You might be able to achieve that client-side by setting DetectableAutoRepeat[0], ignoring the server repeats and rolling your own with a timer. I'm not sure how much of a good idea that is though. On Wayland, key repeat is left entirely to the client, with just rate/delay sent by the server, and the behavior is not specified[1]. I don't think this was intentional btw - just no one considered the multiple-key repeat option. So there you are free to do as you wish. But most toolkits implement the simple behavior AFAIK.
