ABSTRACT:
An improved keyboard assembly is provided wherein a partition is positioned between adjacent keys and prevents an inadvertent simultaneous operation of two or more keys. The paartition can be advantageously utilized to control the cursor moving keys on a word processor keyboard thereby permitting the keys to be closely positioned adjacent each other while insuring only the desired key will be activated.
