Cennydd Bowles thinks:
Users used to tap phones and click mice. But the latest high-end devices combine the two, and it’s now highly likely your interface needs to be designed with both touch and mouse/trackpad in mind. So, unless I’m sure only one applies, I’ve stopped saying “click” and “tap”. Instead, I say “select.’
That’s smart thinking, but I’m not convinced “select.’ is the right word either. I can’t imagine talking an ‘average“ person through an interface and saying “Now ‘select’ the Submit button to buy (those ape action figures).’” That’s why I’m going with “press.’ because whether on an input type is physical or virtual, keyboard, d-pad button, trackpad or mouse, that’s what people do.
