Abstract
Abstract A bag-like envelope is sized to receive a keyboard. The envelope has a reclosable and resealable opening for receiving the keyboard and another sealable opening for the electrical cable from the keyboard. A transparent panel of the envelope overlies the keys on one face of the keyboard. Air is evacuated from the interior of the envelope to cause the transparent panel to be drawn down onto the keys on the keyboard.
