Today I saw this tweet about Org entities:
M-x org-entities-help is your #orgmode buddy

I didn’t realize how much I needed
org-entities-help. It’s pretty easy to enter many of the common Unicode characters into an Org buffer but I usually didn’t know or had forgotten their names. With
org-entities-help you get a nice (Org) buffer with the entity, its Org code, its code, and its HTML code.
I’ve been maintaining bookmarks to Xah Lee’s HTML/XML Entity List and a cheat sheet for the last two encodings but didn’t have a handy reference for the Org codes. Now I have all three in a single handy listing that I can bring up at will. If you do a lot of writing in Org mode you really should check it out.
