Instead of using a button labeled "A11Y" to auto-calculate tab order, label it with something that makes it clear what it actually does.
Possible labels:
- "Auto-calculate tab order"
- "Accessible tab order"
- "Accessibility"
Currently it requires two tooltips to explain what it does!
A11Y button requires two tooltips to explain its function.
App creators at my organization have been ignoring that button because it's tiny, cryptic, and not in a location that makes sense. (It would probably be used more if located near the page outline instead of grouped with the zoom buttons.)
I think the use of "A11Y" when you mean "accessibility" makes sense for casual discussions and contexts with character limits, but it can also be jargon-y, confusing and excludes anyone who isn't "in the know". If you want people to use this tool to create more accessible apps, it should be immediately understandable. Even The A11Y Project recommends writing out the whole word when possible.
