Keybind A-Up and A-Down does not work

[phellarv]

When I try to add: [keybindings] focus-next-channel = A-Up focus-prev-channel = A-Down

in the config.ini, it does not work. It removes the current binding, but it does not add the binding which I try to add.

Hi @phellarv. Different terminals send different sequences for certain key and modifier combinations and Matterhorn's terminal input processing might not recognize those sequences. What do you get when you perform these steps?

• Run cat >/dev/null
• Press A-Down

For example, when I do it, I get this:

$ cat >/dev/null
^[^[[B

Let me know what you get and then I'll see what we can do from there.

Hi,

Thanks. Here is my results from /dev/null

$ cat >/dev/null
^[[1;3B

I hope that gives you something to work from.

Okay. Given that, I think the steps described in this FAQ entry ought to be helpful. Can you take a look?

Hi, I did the steps outlined in the FAQ, and ended up with a ~/.vty/config with a content like this:

map _ "\ESC[1;3B" KDown [MAlt]
map _ "\ESC[1;3A" KUp [MAlt]

But no cigar. Alt-Up and Alt-Down does not work.

I tried to see if there was a possibility that I could get some debug from matterhorn, and ran VTY_DEBUG_LOG=/tmp/matterhorn-keys-debug matterhorn. But that did not produce any logs.

Please advice on how to dig further, or tell me where I went wrong.

[phellarv]

By the way - I tried MMeta instead of MAlt, but still nothing.

Hi,

I think I brainfarted. But anyways. This combo works now: ~/.vty/config

map _ "\ESC[1;3B" KDown [MMeta]
map _ "\ESC[1;3A" KUp [MMeta]

~/.config/matterhorn/config.ini [keybindings]

focus-next-channel = M-Down
focus-prev-channel = M-Up

Thanks for pointing me in the right direction.

I'm glad to hear that you've gotten it working!
