when applying an expression (a preset from elsewhere) and then clicking the twirl down arrow of the property in question, I see the first line of the expression code. When double-clicking this line, the whole expression twirls open. Then clicking the arrow closes the expression, and clicking again, the whole expression is again opened.
How would I get the expression back to its original state, so that clicking on the twirl down arrow of the property would only show the first line of the expression, rather than all of it? Thanks.
