aftertouch

Pressure sensitivity on an electronic synthesizer, allowing the musician to change the tone or sound of a note after it is struck.

A touch (feature or characteristic) added finally or as an afterthought.

A feature in football/soccer games allowing the player to swerve the ball immediately after kicking it.

KO2 ruins every other football game you'll ever play; I never got good at SWOS - the controls were all wrong. And the aftertouch was stupid. And the computer keepers were always hopeless on free kicks.
