How to disable Pentadactyl per site?

Is there a more definitive way to disable Pentadactyl on a url basis that is not -- PASS THROUGH -- ?

When I try to use codepen.io I cannot edit any text fields, with or without pass-through enabled. Any ideas that are not as drastic as going to the add-ons page to disable Pentadactyl would be greatly appreciated. I know Vimperator has this feature, does Pentadactyl?

I think pass-through will work for you if entered early enough. I've discovered on Google Docs that if I manually enter passthough I still can't type, but if I reload the page with pass-through enabled things work.

You can take advantage of pentadactyl's :autocmd feature to run the pass-through command automatically based upon a URL regex. For example, to disable pentadactyl on Google Docs you would enter the command

:autocmd LocationChange 'https://docs.google.com/*' :normal! <C-z>

You can make these changes permanent by saving these commands to your .pentadactylrc file.

If you want to disable certain keys for a site, you can use passkeys. For example,

:set passkeys+=codepen.io:<Esc>

will pass the Escape key through on CodePen.

If you give me more details, I might be able to give a better answer. You really should be able to use CodePen with or without passthrough-mode enabled. (You'll want it enabled if you use CodePen's vi bindings.)
