Realized there was a bug that prevented this from working in FF 2.0x. Current version should now be fixed.

Its not for the roster -- its for the sit or start feature (or the player ranker, or now, the team ranker) -- in tools. The initial version did not allow keyboard commands. The current version is too sensitive for my tastes (I prefer using enter/return to submit the choice, rather than just the keystroke).

Updated script to include team ranker

Right -- this is for the classic version only.

Instead of hardcoding the begining of the URL (us.f811.mail, which will fail for the vast majority of users), you should use compose.mail.yahoo.com
