I agree that hot key discoverability could be better, but I don't think
this is an issue in the PostgreSQL documentation; it's something the
browser should handle. The job of the HTML markup is to declare the key
-- then it's up to the browser how to present it. Otherwise, every
single web page in the world (well, those with hot keys) would have to
repeat this analysis, which seems on the wrong level to me.
