Once in a while, I am afflicted by Accidental Caps Lock On syndrome on my Happy Hacking Keyboard. It does not happen to me often, but when it does, I usually do not remember how to toggle the Caps Lock off and I need to re-search how to do this again.
To put an end to this pointless search, here's how to toggle Caps Lock on and off on Happy Hacking Keyboard; press
Shift + Fn + Tab.

I'm still wondering what's causing me to press this key combination by accident in the first place.
