Using hotkeys to move between tmux panes

I'd like to use the same keys I use to switch focus between windows (`alt - up`, `alt - down` etc...)
to switch focus between tmux panes.

Now I don't know if this is a): possible at all, and b): something to be handled by skhd, but I'll try to explain what I do now and hopefully someone can put me on the right track.

Switching focus between tmux panes is done by pressing the prefix key, by default `ctrl - b`, followed by the arrow key (up, down etc...) corresponding with the direction of the window one wants to focus.

Instead of pressing ctrl-b and an arrow key all the time, in my alacritty config file I have set a key binding so that when I press, for example, `cmd + alt - up`, alacritty sends the code `\x02\x1b\x5b\x41`, which corresponds to `ctrl - b` followed by an up arrow.

So to switch between windows I need to press `alt - up` and to switch between panes I need to press `cmd + alt - up`. While this is an improvement from the default way, it's still counterintuitive.

Is there a way to implement this?

The issue does not name a source file, test, or implementation entry point. Start by tracing how skhd handles key bindings on macOS and compare that with the alacritty key sequence described; done means establishing whether the requested direct hotkeys can be supported and documenting or implementing a clear behavior for switching tmux panes.
