Fill in the blanks: Let user escape / character
A user wants to use the "/" character to write fractions in fill in the blanks, but the "/" character is reserved for separating alternatives. There should be a way to escape the slash and colon.
See forum post here.
Add syntax to escape the slash character.
Escaping * would also be useful.
In general, the places we are using reserved characters for parsers, we should include some way to escape the reserved character.
