Is there a way to remap arrow keys with pressed Ctrl or Alt to something else? Ideally it would be <nop> becouse right now after pressing Ctrl + <right> Vifm copies current file 5 times.
showkey -a tells that Ctrl + <right> produces ^[[1;5C which explains Vifm's behavior.
Ctrl + <right>
You can map such sequences by using <esc> instead of ^[:
:noremap <esc>[1;5C <nop>
Perfect. Thank you.
