Err, that's not all it takes to run an editor :) File opening and
saving would be kinda helpful, for a start...

But that's what I meant when I said that a multi-line entry field is
an extremely standard widget. (I'm a bit surprised that PgUp/PgDn
don't work, but the rest of what you say is perfectly standard.) It's
a bit harder to do an editor that doesn't just call on a GUI, and more
importantly, "tk.Text().pack()" does not make the world's best editor.
But it sure is handy when you want to embed an editor in something
else!
