Window picker with hints for Awesome
Put hints.lua in the awesome config directory (~/.config/awesome)
Load hints module (in rc.lua):
require("hints")
Initialize (in rc.lua, must be after beautiful.init()):
hints.init()
Add a keybinding to run hints.focus() (in rc.lua in globalkeys declaration):
awful.key({ modkey }, "j", function () hints.focus() end),
Now, when you press modkey + j, letters will pop up on each window and you can select a window to focus by pressing the corresponding letter.
