How to delete or Rename a variable

As I was starting to develop the app, I have added many variables. Now I have simplified the app and there are many unwanted variables in the app. How to remove them or rename them so I can use them for other purposes?

It’s not a problem to have unused variables but if you want to, you can rename them by typing a new name into the Initialize block for each variable.

Thanks, They won’t eat the memory space right?

I don’t know the details but I can’t imagine unused variables use much storage space at all.

I’ve deleted the initialize variable blocks. But the variables are still there. How can I rename them?

Can you post a link to your project and let me know the name of a variable that is “still there”?
