Keybindings

Press <Super> + <S> ;)

But in case you want to change your keybindings its pretty simple.

Go to /mappings/ and open either the global_keys.lua or client_keys.lua

The global_keys are for every keybinding that does not rely on a client or widget and can be done at any moment e.g. open rofi, change volume etc

The client_keys are for clients specifically, for example to move them around, close them etc

You are going to find something like this:

awful.key(
    { modkey },
    "#44",
    function()
      awful.client.focus.byidx(1)
    end,
    { description = "Focus next client by index", group = "Client" }
  )

The modkey is defined in the user_variables.lua, "#44" is the keycode, so it works on every keyboard layout, but you can just as well write "a", "5" or "return".

After this comes a callback function where the magic happens, do whatever you want this keypress to do.

client_keys.lua gets a "c" in their callback function, this is the client that was focused while pressing the key.
