Control key sequences (e.g. Ctrl+K) are not repeated when held down over SSH

[og900aero]

When using st flexipatch to SSH into a remote Linux server and running Micro text Editor, holding down a control key sequence like Ctrl+K (used to cut a line in micro) only triggers the action once, instead of repeating it continuously as long as the key is held.

However, when using the same setup with Alacritty, Ctrl+K is repeated as expected while the key is held.

This issue is not present when using local shells without ssh.

Is there a setting for this?

Good question. Not my area of expertise so not sure if I'll be able to help.

In my experience when connecting to remote servers using ssh there are often programs that make assumptions based on the TERM environment variable and most workarounds involve changing this to be "xterm" to pretend that all capabilities are available.

The TERM environment variable can also affect stty in odd ways.

What you can check on the remote server is what the output of the two commands are;

echo $TERM
stty -a

and compare the output when using st vs Alacritty.

The term variable is different: st-256color vs alacritty, but ssty -a gives the same output:
╰─❯ stty -a

OK, does explicitly setting the TERM environment variable to "xterm" before using ssh make any difference with regards to repeating keypresses?

Yes. If I change it to xterm, ctrl+k repeat works perfectly.

Then you know what the workaround is at least. I suppose you could try to narrow it down further if you have a particular interest, but not sure if that will change anything in the broader perspective. Most likely you'll be forced to use the workaround either way.

Okay, thank u for your answered.
