The attached macro is designed to change case for highlighted text. When I run it, it takes several seconds to produce output (like 3-4 full seconds). If I manually copy the text to the clipboard, it produces output faster, but it is still slow. What changes can I make to the macro to make it produce output faster? Thanks.

Hmm, after testing I am actually getting delays with other macros. How to troubleshoot? The computer is fast in general with other clipboard-related scripts, etc.

it happens every time I run it.

Thanks, here it is.

Seems to fix it, thanks.
