49d# 256 constant keymap-size
50
51\ This defines the format of translation tables.
52\
53\ A translation table is 256 bytes of "entries", which are bytes
54\ (unsigned chars). The entries are decoded by keyboard.c.
55\ The Sun serial keyboard only needs 128 entries but USB requires 256,
56\ since we only have 1 keymap NVRAM variable, we have to use 256.
57\ If the entry is less than 0x80, it is sent out as an ASCII character.
58\ "Special" entries, 0x80 or greater, invoke more complicated actions.
