Allowing Gmail keyboard shortcuts to pass through Pentadactyl
If you’re using Pentadactyl and you’re bothered by the fact that it keeps eating your Gmail keyboard shortcuts before Gmail can see them, then you need to set a passkey for Gmail. I had trouble finding the correct syntax for this, but here it is (just throw this into your ~/.pentadactylrc and restart Firefox):
set passkeys+=mail.google.com:jkroae<CR>,gi
Note that all the characters afte the “:” are the characters that you want to be allowed to pass through. Feel free to add or remove characters from that list based on which Gmail keyboard shortcuts you use and which you don’t.
