Abstract
In an example, a light blocker may comprise a bellow to extend from an outer edge of a key to an inner edge of a key window to span a key gap in between the key and the key window. The bellow may extend along a periphery of the key, and the bellow may block light originating from under the key from passing through the key gap.
