The Expressions Thread

Really great thread you’ve got there felt_tips! I am quite new to expressions and wonder if there is a way to change multiple instances of text at once? In my current project I’ve got the following:

All of these text lines are in one single text layer. I want to give buyers an easy way to change all of those lines of text within a few seconds instead of highlighting every single line (in this case “your text here”) and typing in their desired text. Is there an expression that could do this for me?
