	4 Subject: [PATCH] Add toggle colorscheme functionality
	5
	6 This patch is meant to be applied on top of the "inverted colors" patch
	7 (https://tools.suckless.org/sent/patches/inverted-colors/). It creates a
	8 new binding, "i", that lets you toggle between two colorschemes during
	9 presentation.
