tldr; Rich Text Fields use Markdown
I was writing a solution to a User Request problem into our homebuilt ticketing system. It has to do with applying '_curuser_' to a custom Role permission. I noticed that as soon as I hit space after the last underscore, the text changed. This is unexpected behavior and in this case undesireable, I want to maintain the syntax of the custom rule.
Today I learned something new and want to share it in case like me you had no idea this would happen. If you type certain characters in a specific order into a Rich Text field, the text changes formatting. Below is a table of all the examples I could find. The left column is preceded and ended by a single quote which causes the text to stay unchanged. The right column is the same syntaxt without the single quotes, note how the formatting is changed.
~ since this Website won't allow some of the characters I inserted an image, sorry to those who like to copy and paste for thier own notes.
