Feature Request: Ctrl + Backspace (or Delete) to clear a word

[AmethystGosling169]

Fish shell environment already supports this in a few terminals.

Would be interested to see this support implemented for kmscon, potentially for other shells too (or even shell agnostic).

This should probably be default behavior, a great addition as kmscon is trying to be modern.

I think the problem is that libtsm sends the same control sequence regardless of the modifier keys:

libtsm/src/tsm/tsm-vte.c

Line 3007 in 8a40f0b

if (vte->backspace_sends_delete)

For some keys like page up, the modifier keys are taken into account.

libtsm/src/tsm/tsm-vte.c

Line 3074 in 8a40f0b

Do you know what should be sent to fish, to have ctrl+backspace working ?

[kdj0c]

In fact it already works in kmscon, using alt+backspace, or ctrl + w.
There is no standard way to send crtl+backspace, so I'm not sure it can be done without breaking other terminal apps.

As far as I know the way most terminals send ctrl+backspace is via Kitty's keyboard protocol (see kmscon/kmscon#461).
