% Description       TeXstudio shortcuts cheat sheet
%                   Version 1.2b
% Notes:            Inspired by:    https://tex.stackexchange.com/q/365456
%                   See changelog:  https://pastebin.com/U7r8ug5t
% How to use:		1. Place \rowcolor{impt} in front of rows you want to highlight
%					2. The colour of 'impt' can be changed under `Table settings' -> \definecolor{}
%					3. Add your own shortcuts in the last table. 
%					   Note the shortcut macros defined under `Shortcuts for the shortcuts'.
% Boring Stuff:		Feel free to use this anyway you like. :)
