Arduino has two reset options I know of:

• single click restarts existing program
• double-click listens for an upload for a few seconds, then restarts existing program

Is there another option to have an existing program erased or replaced with something benign like a blinker, e.g.

• triple-click erases existing program and listens for upload indefinitely

If not, what is the level of difficulty to modify the standard bootloader to implement this option?

NOTE

The rationale for this option is to recover a bricked board, e.g. with USB port turned off by a low power mode, so the regular software upload doesn't work any longer, at least without some trickery.
