Some applications may expect to use keys that exist on one of the keyboards but not the other. In most cases, if a key does not exist on the keyboard in use, it is still possible to use some other key that is equivalent. To do this, it is necessary to know which keys are equivalent on the two keyboards.
There are 14 keys on the C1429 keyboard that generate keycodes equivalent to keys on the 46021 keyboard, but have different engravings on the keycaps. Some have the same key symbol on both keyboards, while others do not. These C1429 keys, their 46021 equivalents, and the corresponding symbol names are shown in the following table.
