So I know of two ways to lock the buttons:
1. Under system settings->Auto-lock (during activity, etc) I have it still set to Off.
2. CTRL->Lock Keys.
However, I've been hesitant to try these because I've been unable to find information on how to unlock the buttons.
So...how do I do that?
And is every button locked when that's on? ie: I have no ability to manually set a lap if things are locked, right?
