Why not use the TextView's buffer's Modified flag?
(The reason you can't capture all the keystroke events is that the
textview is subscribed to the key events itself in order to capture
key input, and when it "consumes" keystrokes it prevents the event
from propagating to other handlers. You can work around this, as Chris
said, by putting the [GLib.ConnectBefore] on your handler, which
causes GTK# to insert your handler *before* the widget's own handler).
