Triggering Two Actions Simultaneously

I am looking for a solution for triggering two actions at the exact same time. Right now, the buttons are being triggered in quick succession, but I would like for them to be simultaneous. Is BTT able to do that?


Do you have an example for what you want to achieve?

In Pro Tools 11, I would like to switch to the smart tool with a touch bar button. Switching to the tool requires a simultaneous press of F6 and F7, but when I program the button to trigger both, it triggers them in quick succession, not simultaneously, and a different tool is picked.
