[orca-list] Advice on clicking clickables in Firefox?

[Nolan Darilek <nolan thewordnerd info>]

Switched back to Linux recently after a couple years on Windows and 
NVDA. Please don't get the impression that this is a Windows/NVDA fan 
post--I switched back to Linux because Windows itself irritated me--but 
I'm hitting a few pain points that just aren't going away using Orca 
after being away for nearly 2 years.

Clicking clickable text in Firefox that isn't a link is one example, and 
the most painful aspect of it is that I can't come up with a reliable 
test case. I position the caret on the text to be clicked. I then use 
the Route Pointer command (which I think by default is something like 
caps-9 in laptop mode but which I've rebound to caps-backspace) and then 
simulate 1-2 left-clicks.

And here is where things diverge. Sometimes it works. Sometimes nothing 
happens. Sometimes, despite the fact that I've pressed the route 
command, clicking opens the overview panel, takes me to another app or 
performs another action. I was trying to order food on Grubhub last 
weekend and spent 15 minutes trying and failing to click menu items 
before giving up with Linux for that task.

I ultimately had to switch to Firefox running under NVDA in a Windows 
VM. Under NVDA, pressing enter on a clickable item almost always 
triggers a click on that item. While the Grubhub ordering process wasn't 
the most accessible, I didn't experience this routing issue at all when 
I could simply press enter to simulate a click.

Is there some secret to accomplishing this? Ideally I could complain to 
every website/app in which this behavior occurs and tell them that 
clickables should be either links or buttons, but that would be a 
full-time job, and pragmatic me just wants to get the task done. :)

Also, is there some reason that pressing enter in Firefox can't trigger 
a click under Orca? That to me seems like the most pragmatic solution. I 
don't want Orca to be an NVDA clone but when one or the other does 
something useful, I'd hope that the other might copy the pattern. UX 
will of course differ between Linux and Windows but conventions can 
cross over and be incredibly useful. The reason I point this out is that 
I'd really like to shut down my Windows VM, but as it stands it's 
running almost constantly so I can switch over and use websites that I 
can't get working under Orca.

Thanks.
