How to have melee automatically "Interact with Target"

[Fizzler]

What was the mod? There might of been a mod but blizzard turns off functions all the time so might of been disabled at some point.

button:RegisterForClicks("AnyUp")
button:RegisterForClicks("AnyDown")
button:RegisterForClicks("AnyUp", "AnyDown")

Blizzard allows addons to take advantage of keyup and keydown this is not restricted at this time. Macaroon does this today as does Snowfall keypress
