| Method for switching a plurality of key functions allocated to a special key |
|
A method for switching among a plurality of key functions allocated to a special key, whereby the occurrence of a phenomenon that is contrary to a user's intent can be prevented. When a key event detector 14 detects the depression of a special key, it sets a register 18 by which a request is asserted to output a make scan code that is supposed to be output when the special key is independently depressed and that is originally allocated for the special key. A key event analyzer 15 and a code generator 16 output a scan code to carry out a predetermined key function in response to the depression of a key. But if the register 18 is set when the special key is released, the key event analyzer 15 and the code generator 16 output the above described make scan code.
