	#
	# Expects to find a file titled something like cover.jpg (see prefixes,
	# middles, suffixes below) in the same directory as the music file. If found an
	# image viewer is launched. If no DISPLAY is available, use img2txt to get
	# ASCII art if available.

United Kingdom Dvorak 105-key keyboard layout file for Mac OS X. Put it in ~/Library/Keyboard Layouts, clear the cache (sudo rm /System/Library/Caches/com.apple.IntlDataCache*; sudo find /var -name "*IntlDataCache*" -delete) and then it should be in the keyboard layouts list as GB Dvorak.

	# - The visibility property is totally ignored whether visible or hidden
