The course I'm currently taking makes me uses symbols like the biconditional, xor, and quantifiers. Each symbol requires an entire word to type out but I also frequency have to look at a reference sheet to find the command for each symbol.
I just use short hands like "-" for not, "and" for $\land$, etc. I'm sure if I used LaTex more often, I would have most of the commands memorized but I use it infrequency so I almost never remember.
If any of you know don't know what LaTeX is, it's a way to write documents, it's usually used to write Math and Science research paper's because the of the formatting and symbols LaTex allows for. It has a lot of flexibility, but everything in LaTex requires a lot more effort to type then in something like MS Word. I have to use it for a class I'm currently taking where you have to do super long proofs, I created a short 50 line script where I can enter a mathematical expression using plain text and shorthand's for special symbols and the function returns a string I can copy and paste into LaTex. Saved me and my groupmates multiple hours, I also posted on my class forum so I can save my classmates the pain as well.
