PAID Project, custom keyboard strokes using a 3x4 matrix keypad

I need help creating code for a small pay phone hack. I'm using an Arduino uno, 4x3 matrix keypad with 7 leads and a GND. I want to have the keypad input custom keystrokes into the computer.

I've been able to find other information on using regular input buttons to make keystrokes like shown here :Arduino Project Tutorial: Macro Keyboard - YouTube Just not using a keypad.

I need to have the the computer recognize the Arduino as a regular keyboard like shown in the above tutorial.

I need to be able to customize the keystrokes for each button on the keypad.

Let me know how much you're will do do this for and if you need any additional information or specs.

Where the input comes from is COMPLETELY irrelevant when deciding what to do with the input.

In his defence, reading a key matrix is different from reading a discrete switch. Not by much, but it is different.

A key matrix is different from a regular button input.

So? My point was that once you know what to do, because a key on a matrix was pressed, or because a switch was pressed, or because a roll of some dice came up 11, doing it (whatever it is), is completely separate from how the decision to do it was arrived at.

Your point being? OP seems to know what to do when a particular input is received. My point was that all he/she needs to do is get the particular input from somewhere else.

Your reply added nothing.
