Currently with accessibility, you must hit TAB to enable.
I have a client who wants accessibility enabled all the time, without having to hit TAB.
Is this possible?
Absolutely, in fact that's exactly how it works on iOS/Android since there's typically no tab key to press on those devices: https://github.com/adaptlearning/adapt_framework/blob/master/src/core/js/accessibility.js#L266-L288
