Help for specific operations in the app

Good morning,

I'm a new user and I'm trying to learn how the program works...

I wanted to ask what should I do if I want to create an action (for example a function linked to a mouse button) that performs a certain operation in a specific application, possibly letting it work normally outside of that app.

For example, I configured the middle mouse button to capture a screenshot but I would like the middle button in messages to create a new message..

Thanks for the help

Thank you!
