As mentioned, how do I take control of a laptop's keyboard?

the concept is like the following:

the output of PIC16F877A will be the input to the keyboard.

In addition, do I need anything in between PIC16F877A and Laptop to make it
work?

I am new to microcontroller, and I'd found something called "MAX232"

By the way, I'm using MPLAB to program the PIC16F877A.

If possible, can get an example on how to do it?
