I’m afraid I don’t have any…
by the way, I also found this https://wiki.archlinux.org/title/Sway#Keybindings_and_keyboard_layouts and tried for the left arrow key as follows:
bindsym --to-code $mod+Left focus left
but the arrow key is still not detected when the modified is SUPER.
Please, remember that wev does not print the arrow keys when pressed after SUPER is pressed… it is as if they are not simply passed to Wayland, or did I get it wrong?
