GNOME Bugzilla – Bug 740881
Ctrl + Page Up/Down shortcuts not supported

https://developer.gnome.org/hig/3.14/tabs.html.en states the Ctrl + Page Up/Down should be implemented for a tabbed view. Would be nice if gedit could have that too.
Yes, it's a known bug when you combine a GtkTextView in a GtkNotebook: bug #705648. *** This bug has been marked as a duplicate of bug 705648 ***
