Sounds like what Apple came up with for its laptops a while ago,  though in the 
most recent generation they dumped the idea.

A somewhat similar but more primitive thing is found in the DEC VT71/t 
typesetting terminal, which has a row of 16 "User Defined Keys" at the top.  
These have double keycaps, an outer transparent plastic shell that snaps over a 
smaller ordinary keycap with no label.  The idea is that you could make your 
own labels and insert them under the clear shell.  Then again, a lot of users 
simply laid a cardboard strip with legends just above the top row:
