That's correct. That code might be an overkill for people who never needed org entities. I thought that I have never used `C-u` before plain single characters, so why not make use of that in org mode. With that code in place, inserting an org entity is now C-u away :) If I happen to need org

Hi all, The suggestion to use zero width spaces to sort of "escape" stuff in org mode has come up many times. I have started using it a lot and suggest that to other people now. Here is one such recent QnA on emacs.SE: http://emacs.stackexchange.com/a/16702/115 The OP of that question made a

Thanks for letting me know about org-entities. That is awesome. I now know how to escape various characters in general, but unfortunately this does not work within verbatim formatting (which makes sense). Here's a minimum working example: = * Escaping =equal= sign in verbatim formatting.

My most common uses are escaping double quotes (") and equals (=) within org verbatim blocks (=VERBATIM=) Examples: 1. =var=[ZWS]val= 2. =[ZWS]"something"[ZWS]= Here [ZWS] is the 0x200b zero width space unicode char. I found [ZWS] useful as a generic escape char for org mode. There are few
