For its next trick, Apple might be working on keyboards for its MacBooks that change the appearance and functionality of their keys dynamically, depending on context – so the A key could instantly transform into a 9 key, for example.
This comes from a patent spotted by Patently Apple(opens in new tab) (via 9to5Mac(opens in new tab)), outlining a keyboard which would have a flexible backlighting system that could display any symbol on any key. Specifically, keys with “illuminable glyphs that are selectively visible or invisible to an unaided human eye”.
