I was using a platform called "Obsidian" to take notes and I downloaded a plugin called "Quick maths" where you could write something like this:
$$
al:\alpha;
be:\beta;
ga:\gamma;
$$
and if you were working on a .tex using math or equation enviroment($$) you could just write "al", then using space bar transform it to "\alpha". This way taking math notes gets so fast if you use repetitive notation.
I was wondering if it is available another similar feature in Overleaf. Thanks for your help
