My logic for determining if a GUI is keyboard driven is pretty simple: if I can fire up a screen reader and completely drive your UI via the keyboard, then by definition your UI is keyboard-driven. If your app ever requires me to emulate mouse clicks to drive it, then it isn't entirely keyboard-driven and that should probably be fixed. This is even something that can be measured/tested for on platforms like Windows where you can both read the accessibility tree (which in itself is amazingly powerful particularly for testing) but you can also simulate arbitrary input.
