From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I find the whole "Ctrl+b followed by another key" way of navigating tmux to be too cumbersome to warrant a switch away from something like Tilix where I can hit Ctrl+Alt+| and the screen splits vertically, or Alt+Left to switch to the terminal on the left. I think it's the mandatory release of all keys followed by more keys that does it.

Is there a way to tell tmux to understand that "Alt+Left means switch to the terminal on the left" and bypass the whole Ctrl+b song and dance altogether?

There's no need to get snarky. I did in fact do multiple searches, but as you might note from the question, this is a hard thing to search for. The GitHub wiki has this page which looks promising, save for the disclaimer at the top claiming that it's no longer relevant due to something called extended-keys, but searching the same wiki for that returns nothing. Similarly, a web search for it returned a bunch of news sites talking about how tmux does extended-keys now, but none of the ones I found explained what this was, how to use it, or even if it was relevant to my question.

I too have found searching for tmux information online to be difficult. This recent change to my dotfiles I could never really figure out because it wasn't really documented anywhere except a reddit post and a PR. https://github.com/dannyfritz/dotfiles/commit/c7c9272dfdf46e4526264ffdf3d4b64b4a629a2f
