Web site MacRumors.com has obtained another Apple internal document from ‘multiple reliable sources’ that confirms the company did put a membrane around and inside the MacBook’s keys to try and cut down on dust and debris from getting inside. The internal documents are for Canadian, European, and United States MacBook Pro Service Readiness Guide.

The document for the European and Canadian version outlines the following:

Keyboard and Keycaps
The keyboard has a membrane under the keycaps to prevent debris from entering the butterfly mechanism. The procedure for the space bar replacement has also changed from the previous model. Repair documentation and service videos will be available when keycap parts begin shipping.

While the U.S. version of this Service Readiness Guide does not mention the membrane, it contains a link to a separate internal document titled “Butterfly Mechanism Keycap Replacement MacBook Pro (2018)” that does:

Caution:The keyboard has a membrane under the keycaps to prevent debris from entering the butterfly mechanism. Be careful not to tear the membrane. A torn membrane will result in a top case replacement.
