My screenshot is a bit different because I am in Split View, you are in Code View.
I'm using Wappler 7 Beta 18.
Just click any where inside your code (or select some code) and hit cmd+f. Maybe try resetting panel sizes in the Wappler settings? Maybe it is just hidden?
Find and Replace was never in the Edit Menu. There is a panel for it.
Ok, that's what it was. I did not have any text selected within the code view. Once I selected some text and did cmd+F, it appeared as I was expecting. I don't remember needing to select text to be able to use Find/Replace before, but that's easy to remember.
I knew it had be something simple. Thanks so much Brad!
