Just wanted to report that under FC3, LyX isn't able to use dead keys like ' ` ^ and the like. Also in math, ^ doesn't produce a superscript. Annoying.
It's a qt-3.3.3-<something> bug known as 141475 by Red Hat's bugzilla: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=141475 This is going to become an issue on the users' list... (This also reminded me how VERY VERY VERY unhappy I am about Math not having its own top-level menu entry anymore. It is such a separate and special part of both LyX and LaTeX, that this old practice was more than justified. IMHO of course.) - Martin
