What's a safe way to reduce the delay between duplicate keys?

[IndigoGollum]

I'm working on a new layout that has two copies of most keys, and i noticed last night that pressing two identical keys too quickly only prints the keys' character once. I'm on Linux so my first response was to use linux-x11-repeat-delay-rate, which does work, but also breaks the emergency shutdown shortcut (#1464).

My next idea was to make every pair of keys switch to a new layer when held, in which the only difference is that key's pair is replaced with a rpt key, which do not have the delay issue. I think this would work, but i thought i should ask if anyone has a better idea before i go make 20 or so new layers.

Out of curiosity, have you tried using multi to wrap the key you want to emit? I've seen it used as a workaround for a few things in the docs, I wonder if it would help in this case as well.

Maybe something like

(fork a rpt (a))
