Thanks to Aaron F. about telling me about Typinator (which is a nice text expander for Mac), which allows me to write more readable LaTeX by using Unicode (think μ(θ) vs. \mu(\theta)), which has been helpful.
It took a little getting used to, and a bit awkward when I made my keystrokes with colons instead of \ for LaTeX, so :mu for μ. It’s helpful to see these symbols in latex, but it’s invaluable when trying to annotate pdf notes from professors. One of my goals this year was to go almost completely digital with respect to notes. I have done a lot of it, and find sometimes it’s faster (think of copying and pasting whole equations when people are writing on a board), but has caused a lot of hand cramps.
Disclaimer: there are other text expanders out there (AutoHotKey for Windows) and Typinator is pay for, otherwise it has pop-ups somewhat infrequently when you use a set number of characters.
