Can't map Ctrl+M/Enter (in the `keys` table)

[Andrew15-5]

I wanted to give this client a try, but immediately faced the keymap problem. It looks like for some reason Ctrl+M keymap is treated like Enter desp... ok, it looks like because it is Enter: https://www.physics.udel.edu/~watson/scen103/ascii.html. I'm guessing it's an upstream issue then?

config

[keys]
focus_guilds_tree = "Ctrl+R"
# focus_messages_text = "Ctrl+M"
# focus_message_input = "Ctrl+F"
focus_messages_text = "Ctrl+F"
focus_message_input = "Ctrl+M"

Also looks like (Ctrl+)Shift/Alt modifier(s) doesn't work. At least for a few keys that I tested it with.

P.S. I recently switched to Engrammer layout and wanted to map Ctrl+rmf for the first 3 focus functions (just like with harpoon in Neovim), but looks like m wouldn't be supported for a while.

Edit

I ended up with

focus_guilds_tree = "Ctrl+J"
focus_messages_text = "Ctrl+A"
focus_message_input = "Ctrl+K"

for now. It's like pressing ←, ↑, and → — very intuitive physically (but not "lettery-based").

Unfortunately, that's how terminals work.

Hmm, I guess it really is not possible. I tried binding it in Neovim and Zellij and nothing changed. I didn't really have this issue before, but now I know.
