"Recolor" is non-standard and counter intuitive
Hi, I found this: https://www.noudaldenhoven.nl/wordpress/?p=166 today in my search on ddg "zathura dark mode" I think we should rename it to invert colors and bind it to ctrl+i instead.
I also think we should mention "dark mode" in the manual/man page to make it easier to find when searching. WDYT?
