I am trying to achieve keybindings like ctrlshiftk to work in Linux tty console (Arch Linux) for usage in editors. For this, the only solution seems to be custom keymapping with loadkeys.
Here's how I successfully did that with ctrlshiftleft:
control shift keycode 105 = F204
string F204 = "\033[1;6D"
For ctrlshiftk, it should be
# legend: 107 is ascii for k, 75 is ascii for K, 37 is keycode for k, u means unicode, 6 means ctrl shift, 2 means shift
control shift keycode 37 = F205
string F205 = "\033[107;6u"
(source)
But this only prints 7;6u when I press it.
107;2u, 75;6u, 75;2u also did not send ctrlshiftK. Keymaps manpage did not help me out either.
I also tried tmux inside an fbterm framebuffer where it then does not print 7;6u but simply does not do anything.
How does one achieve this?
