user keys

[orcinus]

My point was more along the lines of - no, touch screen (and mouse driven) UIs aren't the same as a keyboard w/ regards to long presses. A long press is fairly common in a different context (drag, drag and scroll throug a menu, drag and drop) in touch/cursor based UIs.

Long presses on a keyboard, on the other hand, are *very* uncommon, except for modifier keys (which are easily excluded) and are thus extremely hard to mistake for something else, as long as the length of what constitutes as a long press is longer than a common keypress (which is very short, even with a debounce period included). Think 1 second.

On top of that, asking for a long press is very different than having separate keyup and keydown events exposed to the (user accessible) programming language. Former implies a fixed "long press" length. The latter does not and is infinitely tweakable.
