I need to be able to delete a tree node by clicking on the Delete key
on the keyboard. (Basically, clicking on the Delete key calls a method
which performs the delete.) An explanation and/or example would be
very much appreciated.

Sherri,

What you need to do is subscribe to the KeyUp event for the treeview.
Then, in that handler, if the delete key is pressed, get the current node,
and pass it to the Remove method on the TreeNodeCollection that it belongs
to.

Hope this helps.

Thanks Nicholas!

How do I tell which key was pressed? (The rest seems very
straightforward.)

I'd recommend watching for the KeyDown event. You can get which key was
pressed in the KeyEventArgs object as follows:

    private void MtMessageBalloon_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Delete)
        {
            // handle delete key
        }
    }
