Being involved in the OmniSharp project, I had the pleasure of working a lot with VS Code extension development over the past several years. Given that background, a coworker asked me recently if I had any ideas for improving his user experience with VS Code. In particular, being a screen reader user, he relies heavily on keyboard navigation and being able to quickly move focus between UI elements is critical for his productivity.
VS Code defines a very rich set of commands, to which custom key bindings can be attached, and which can be very helpful in such situations. In fact, through those commands, pretty much any task can be executed exclusively from the keyboard, which can be viewed as very positive from both accessibility and productivity standpoints.
