Comment 1 for bug 834951

Note that group3 has page types Appendix, Chapter, Subchapter, and Blank Tissue.

(See: petabox/www/sf/includes/scribe_keys.xml in the tree, or /var/www/includes/scribe_keys.xml on the scribes.)

So it sounds like 4 key presses are getting in before the page turn goes into effect (a sort of race condition).

Solution might be to rearrange the order of group 3 (as Jesse suggested in email) so that Chapter is first instead of second.
