Keyboard protocol and clipboard key combos (Shift+Ins, Ctrl+Shift+V, etc)

[technige]

I'm currently writing some library code to interact with the (quite excellent) Kitty Keyboard Protocol. So far, most things are working entirely as expected, and comparing my code to a previous version with legacy keyboard handling, my stress levels are way lower!

I've noticed one unexpected behaviour, which could easier be user error on my part, but I can't find any pointers anywhere. I've enabled all the flags as part of the documented progressive enhancement, and all keys are being captured as expected, with the exception of Shift+Ins, Ctrl+Shift+V and so on. For some reason, these still seem to be tied to clipboard operations, so these will insert the pasted text rather than send an escape sequence. The "copy" equivalents send the escape sequences, but also copy the highlighted text.

My expectation was that the "report all keys as escape codes" flag would include these as well, and I don't see a separate flag for clipboard ops. Am I missing something, or are these genuinely excluded from capture?

I've also tried kitten show-key -m kitty and the pasting happens there too, so it seems likely this could be a genuine limitation.

Thanks :)
