I've worked next to someone that was extremely harsh on their keyboard - full blown hammering the keys, with the whole desk shaking - and even in a medium-noise office it was infuriating to work next to.

After a few light-hearted suggestions that he be a bit lighter on the keys, I ended up having to point out how much it was putting me off my work. Thankfully he was good enough to change his habits while he remembered, but he would soon idly begin bashing again.

On a similar note personal space invaders are even worse, but I'll contain my vitriol on that subject for now.
