问题 I built a drag and drop component, and it works like a charm, but now I need to make it accessible for screen reader users. I already have the implementation of the solution done. Basically its a context menu that pops when the enter is pressed and allow to move things around. This works like a charm when navigating without the SR (screen reader), because the implementation that I made listen to KeyEvents (keypress and keydown).
