Hi, I have created a pull request for the pointer cancellation unsderstanding text on the understanding-cleanup branch, incorporating some stuff on the "down event". https://github.com/w3c/wcag/pull/424 This is what I have added: "In contrast, the down-event can occur as soon as the pointer is pressed inside a target. Whether this actually happens can depend on the operating system, the user agent, and the mode of input. For example, the mousedown event will lead to a down-event in desktop operating systems when using mouse input, but will be ignored when using touch input in the same setting. Mousedown is currently ignored in mobile operating systems, but the down-event may be triggered here by the touchstart event, which (as the name suggests) is triggered by touch, but ignored when the same control is activated via mouse or trackpad input." Look at it in contexct of the understanding text: https://rawgit.com/w3c/wcag/understanding-pointer-cancellation-cleanup/understanding/21/pointer-cancellation.html I trust that people more knowledgable than I regaring event handling across devices will weigh in here and correct mistakes if there are any (Patrick?).
