Some Byobu shortcuts not working when using the Secure Shell extension from a Chromebook

us flag

While SSH-ing to a Linux workstation using the Secure Shell Chrome extension from my Chromebook, most of Byobu's keyboard shortcuts work fine (using tmux underneath). One notable exception is Alt+Up/Down for switching between sessions(*), which are interpreted as simple Up/Down key presses and scroll through my bash command history.

How can I have access to switching between sessions on this environment?

Ideally there's some extension settings combination that would fix this, but I couldn't find the right incantation myself (I'm not an expert by any means). But maybe there are other ways or workarounds, like creating new Byobu shortcuts or using alternative Ctrl-a-based shortcuts?.

In case that helps, these are the sequences I get using read -n 1 from the Secure Shell extension:

  • Alt+Up: ^[[5~
  • Alt+Down: ^[[6~

And from a local terminal on the workstation:

  • Alt+Up: ^[[1;3A
  • Alt+Down: ^[[1;3B

(*): Curiously, Shift+Up/Down and Alt+Left/Right work just fine. There are other shortcuts that do not work either, but I'm less bothered by them, like F4-based ones (used by the OS for maximize/restore of windows) or Alt+F11.

Are you using ChromeOS? It is off topic on this site. Only Ubuntu and its official flavors are on topic

I am using a Chromebook to connect to a Linux box, so it's likely off topic. Sorry about that... Could you guide me to which Stack Exchange site would be appropriate for this question?

Thanks, I posted a [mirror question]( at that site. But I couldn't find how to close this one, or mark it as off topic. Feel free to do that, if you can.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
