With exception of the directional keybindings. I wonder how it came to be that the defaults are "jkl;" for the directions instead of the "hjkl" used by everything else (vi(m), less, shells, repls, etc.).

> To move the focus between the two terminals, you can use the direction keys which you may know from the editor vi. However, in i3, your homerow is used for these keys (in vi, the keys are shifted to the left by one for compatibility with most keyboard layouts). Therefore, $mod+j is left, $mod+k is down, $mod+l is up and $mod+; is right.
I wonder where they got that idea. The keys are "hjkl" simply because they were inscribed with arrows in the machine Bill Joy used when creating vi[1][2]. From [1]:
> Joy used a Lear Siegler ADM-3A terminal... the keys h,j,k,l served double duty as cursor movement keys and were inscribed with arrows, which is why vi uses them in that way.
The StackExchange question has a picture of the keys.
Can you send a PR for https://github.com/i3/i3/blob/30e886b0319ee948863a36a65e5b72... with your correction please?
Or do you think that not having arrows on "hjkl" is the justification of using "jkl;"?
Personally, I can't see a good reason for "jkl;". The rationale that those are the keys where the fingers rest has been brought up here, but here is my response:

The thing is that I believe the designers of ADM-3A made a good choice in putting the arrows on "hjkl" as opposed to "jkl;". It's much more ergonomic.
Couldn't think of the right word at the time.
If you're typing with proper form, "hjkl" results in the index finger moving down and the middle finger moving up. So, your most useful finger is used for the most common action, and your second most useful finger for the second most common action. What's probably the third most common action, moving left would be done with your index finger, and right with your ring finger. You'd never have to use your awkward pinky finger for anything.
With "jkl;", you'd be moving down with the middle finger, and up with the ring finger. Your dexterious index finger would be waiting for the moment when you'd want to move left, which is not as often, and you'd be encouraged to use your awkward pinky finger quite often.
This isn't necessarily the case when working with windows, but by now it's a matter of consistency. Although, encouraging to use the pinky finger and not being able to use the index finger for 2 actions still sucks.
