Is there a way to hide an entry field (or any design component) depending on if a key is pressed during startup?

For example, I depress the 'Shift' key and start my standalone APP Designer GUI program. Is there a way for the program to know the Shift-Key was depressed and not show an enter field in the gui, like a secret/designer mode in this standalone GUI app?

If if this is not possible, would a debug flag set to 0 (do not show enter fields) or 1 (show all fields) be another approach?

Thanks!
