How can I get Pentadactyl (a fork of Vimperator) to hint voting arrows on StackExchange?
For example, I want to upvote this question and answer but Pentadactyl does not provide hinting for the voting arrow buttons even after I removed my .pentadactylrc file and restarted Firefox.
Is there any way to view the currently mapped keys in Vim?
I think I'm not getting hinting for any questions but I'm not 100% sure. I've never had problems with Vimperator on StackOverflow and I expect that Pentadactyl should have most if not all of the features that Vimperator does.
I suspect that the description of the hinttags' 'ht' setting on this page describing Pentadactyl settings is the key to figuring this out.

Unfortunately I wouldn't know a CSS selector or XPath expression from my own elbow. Is this the solution and if so, what CSS selector describes a SO voting button? If not, what is the solution?
Run the following command.
:set hinttags+=a[class]
Add this line to your pentadactylrc to make it permanent.
a[class] is a CSS selector in the format tag[attribute="value"]. So it matches all anchor tags with the class attribute on the page.
If you inspect the source of this page you'll see the voting arrows are described with:
<a class="vote-up-off" title="This answer is useful">up vote</a>
If you want to match specifically the voting arrows and star on StackExchange pages use:
:set hinttags+=a[class^="vote"],a[class^="star"]
This uses regular expressions to match anchor tags with class attributes beginning with 'vote' and 'star'.
