keyticle

noun. (kee-tuh-cul)
dry finger skin and fingernail particles that lodge under your keyboard key pads, causing the keys to stick.

If certain letters on your keyboard don't work, it may be a case of keyticle build-up. . Simply turn your keyboard upside down: then shake lightly. This should dis-lodge any keyticle than is stuck under the key pads.
