My watch just stopped. LOL.

I agree. We need the other issues addressed however and group agreement with the approach. In particular, if the user agent is going to assign a key that the author did not choose how would this be discovered by the end user? To me this is a big problem. 

We also need to decide on this fairly quickly. We are trying to lock down 1.1. Dominic raised the issue. I would like to see him satisfied with the solution, or a version of the solution, that Charles is proposing.

That won’t happen for some time as they are trying to lock down the SVG2 spec. Currently, it extends Element:

https://svgwg.org/svg2-draft/idl.html

Also, I don’t think we want accesskey on HTMLElement. There are a lot of elements that you would not want an accesskey on. 

If this is accepted the issue needs to be logged with SVG.

If not, then I would guess that this proposed aria attribute is intended to replicate the functionality. I think we’d want the behavior of @accesskey and @aria-keyboardshortcut to essentially operate in a similar (identical?) fashion.

For example, on most U.S. English keyboards, the percent sign "%" can be printed by pressing Shift+5. The correct way to specify this shortcut is "Shift+5". It is incorrect to specify "%" or "Shift+%". However, note that on some international keyboards the percent sign may be an unmodified key, in which case "%" and "Shift+%" would be correct on those keyboards.
