How to rename a variable



I want to replace all instances of a variable in my document. It’s impossible to do with find and replace because my variable is just the letter e. I see there is a Rename Variable option under the tools menu but I can’t figure out how it works. I highlight the variable I want to replace, click that button, it gets a yellow highlight but nothing else happens. Hitting enter makes the highlight go away, but no changes are made.


for javascript you can edit the highlighted name, and other highlighted names in the same file will be changed as you type.
