There are two basic options for making keycaps, the cheap option involves printing the captions the expensive option is double shot moulding where the caption is part of the keycap. With the cheap keycaps the captions wear off, usually starting much as you describe. The only time I've seen the legend worn off a double shot moulded keycap was when we were attempting to test the key switches, 10 million operations they were rated for! The test rig ran for months and destroyed a good many keycaps completely, a couple of cam timers and no key switches. -- Steve O'Hara-Smith <steve@sohara.org>
