Answer 1

Override the ProcessCmdKey() method of the form. It gets called straight from the message loop, before the keyboard message is dispatched to the control with the focus. Which is why overriding WndProc() doesn't work.

    protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {
        if (keyData == (Keys.Control | Keys.F)) {
            MessageBox.Show("What the Ctrl+F?");
            return true;
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }

Technically, you can also override the form's OnKeyDown method with KeyPreview = true, but that's an ugly VB6 anachronism.
