Trackpad gesture simulating modifier key

Hello. I'd like to have a simple gesture on the trackpad simulate a function key. Specifically, I'll like to click and hold in the upper-right corner and have that simulate the function key down. Therefore, click and hold upper right corner and press the "1" key results in sending function+1. Just as the function key would work, releasing the press on the trackpad releases the function key.

Basically, can presses in certain places on the trackpad work like function keys?

thanks,
