How do I switch between applications for repetitive tasks such as copy and paste?

You might be tempted to try and use the ALT+TAB key to switch between programs. This is actually not always reliable and in fact, will not even work via Macro Express on some computers due to the low level nature of this key command.

Use the ‘Window Activate’ command to switch between windows.

Or review the ASCII File Begin Process help topic for another way to do this without having to alternate back and forth between applications.
