insert mathematical symbol
I am typing a long document in which I need to frequently use the "prime" symbol. NOT a single quote or apostrophe, but an actual mathematical prime. I understand how to do "insert symbol" in MS Word and navigate to the symbol I want, but if I am having to type this character every few sentences or words (I'm talking about the 3 prime and 5 prime ends of DNA), I don't want to have to do insert symbol every time. Because that slows down my 100+ wpm typing to like 5 or 10 wpm and is a big waste of time (time that I am billing to a client, so I am trying to be conscious of it). Is there any way I can do this quickly? Like without using my trackpad at all, just keyboard shortcuts? I'm using Mac OS Sierra. I know two different ways to do this in Windows but not a single one for Mac (unless I copy-paste a prime symbol, which will work until I forget and copy something else...).
