@piggo on windows you press control windows enter, and on mac you press command f5. On most linux distros you should be able to turn it on with super s, or super alt s. Anything after that is actually using the screen reader itself, which is sadly necessary to test functionality meant for screen readers. Building one into Chrome probably won't help you here as it would need to be similarly complex. Otherwise, the functionality you're testing for would be missing in the screen reader. But in Bitwarden's case, turning on any screen reader, focusing the website and pressing tab a bunch would have caught this problem.
