There is a way to do this, it’s just accessed through your Mac settings, on your Mac, choose Apple menu > System Settings, click Keyboard in the sidebar (you may need to scroll down), then click Keyboard Shortcuts on the right. Select App Shortcuts on the left, click the Add button, click the Application pop-up menu, then choose ASP and customize from there.
This might be slightly different depending on your Mac version, so someone correct me if I’m wrong. It’s been a bit since I played around with the Mac version of ASP.
