Control Sequences decoding: in search of docs

[Shoxx98]

I've been searching for a complete character map to each of the key combinations using Control Sequence Introducers, e.g. CSI 1 ; 3C, which stands for ALT+RightArrow on my keyboard (zmk). I take it that these are based off of the xterm definitions and the form of this specific one should be CSI Pm or CSI Ps ; Ps, but none of the specific key mappings are described there (for example what 1 and what 3C is). Does anyone know of a document which describes the standard keymappings? I've read that the specific keycodes are also manufacturer-dependant, but there must be some document containing the specs, so you don't have to craft specific interfaces on either side, right? I am also kind of going through the zmk code right now to understand it a little better. Is this even the right place to ask?

Okay I just found kind of what I was looking for here in the codebase.
