//TODO: Is there productivity gain in the use of unicode?
//	- Won't work in xterm.
//	Create a layer for macros and/or unicode?
//	Are macros useful?
//	- Found no gain in having sendstring for commands.
//	- Find repeated tasks that cannot be done easily on the OS.
//	- Most other keymaps have macros for game/fun stuff, hard to find "serious" onces.
//	Screw Norwegian layout, switch to US with unicode æøå or US/English International?
//	- Will be different from laptop keyboard, requiring a switch on the OS side when only using the laptop.
