The patent that was recently awarded to Apple depicts the inclusion of a display panel on each keyboard keycap. This allows it to change the “print” on each keycap to reflect the character it will input when pressed. On one hand, those that benefit from this may be limited to those who type in multiple languages. But on the other, this will eliminate the issue of getting a laptop with the wrong keyboard layout.
What makes the idea behind this Apple patent even more impressive is the fact that these keys are meant to work on existing keyboard switches. This means that is will be compatible with the scissor switches on the company’s current run of MacBooks. It may also be compatible with other laptops, since scissor switches are currently the most common kind anyway. But as with all patents, it remains to be seen if Apple will be doing anything with it. The incentive to do so is probably there, letting the company spend less on making MacBooks with different keyboard layouts. (Source: USPTO via SlashGear)
