Ctrl-Shift combos aren't recognized by neovim from kmscon

[shmerl]

I noticed that my key mappings that use Ctrl-Shift don't work in kmscon.

I tried testing what neovim sees when they are pressed (like Ctrl-Shift-Right for example).

Looks like Shift is simply swallowed in these combos. At least with Ctrl-Shift-Right / Ctrl-Shift-Left.

It works for example in konsole and xerm. The way to test it:

In insert mode in neovim press Ctrl-V, then press Ctrl-Shift-Right for instance. In konsole it would show: <C-S-Right>, in kmscon it shows <C-Right> which is incorrect. Some other combos don't show up at all.

I think the issue is in libtsm:

libtsm/src/tsm/tsm-vte.c

Line 3064 in b5394a4

case XKB_KEY_Left:

It doesn't handle properly if ctrl and shift are pressed together.
I will try to fix that.
