+* The S-C-t key combination doesn't get passed to Emacs on X.

+This happens because some X configurations assign the Ctrl-Shift-t
+combination the same meaning as the Multi_key.  The offending
+definition is in the file `...lib/X11/locale/iso8859-1/Compose'; there
+might be other similar combinations which are grabbed by X for similar

+you want to be able to bind one of these key sequences within Emacs.
