I'll preface this by saying that I do 508 compliance testing as part of my work as a contractor to an American Federal Agency. 508 compliance is a set of requirements that software must meet as part of the Americans with Disabilities Act. The part I usually work with is software. Most of the items in the list have to do with alternative use of the software for people with low / impaired vision, or physical access challenges. Part of this is that you have to be able to navigate the software without relying on a single method of input.
I find myself being unable to use a mouse sometimes, and still want to play with my music. I think this is how I got stuck with doing the 508 compliance in the first place.
Anyway, I've noticed these issues with using the keyboard as the only means of interaction. I have very little customization, and am using version 3.0.6190. The first items are individual key navigation items that I can't get to work. The tab order issues can probably be explained. Thanks for your time and attention.
--Can't open the context menu anywhere using the Keyboard's "Menu Key."
