Don't use it (version 1.2.20110411) yet. Although a potentially good add-on, ctrl-shift-c is used by Seamonkey mail to mark all your (perhaps years of) e-mail as read. Undoing this in Seamonkey does not seem to work. If you use IMAP as protocol, this marking is done immediate at server level and there is no way of undoing it, except perhaps asking your system administrator to reset all your e-mail. I've informed the author and asked him to choose another key combination for this much wanted program.

This review is for a previous version of the add-on (1.2.20110411.1-signed.1-signed).
