I also use it to switch out of a virtual machine in VirtualBox.
But back to the original question, in Linux, replace Caps-Lock with a Compose key by setting it in [Settings][Input Devices][Keyboard][Advanced][Position of Compose Key][Caps Lock] and then enjoy being able to type any accents or weird letter very simply.

When I go to war... I go to WAR.
I wonder if we are still going to war. We do a few 'surgical' drone strike that take out one or 2 guys and leave the rest of the family alive (and angry). But it used to be that you'd burn to the ground entire cities, where the few survivors would be only too relieved to see you coming and not shoot them afterwards. I wonder if we are going towards a state of perpetual low level warfare. At least when you wipe out an entire country you have a generation or two of peace afterwards. I think we are improving but I'm not so certain. Remember, a massive amount of violence solved the nazi problem.
