Using my micro board to trigger an MP3 sound card

No, no, no. You don't program the IDE. You use the IDE to receive keyboard button pressings and store them as a text file used for later adventures like compiling and downloading.
Any word handling program could be used in that first stage. The IDE is just a text editor. Suppose I use Word when typing the sketch. Am I "programming" Word? Certainly not.

I've seen question where people want to "program" just anything, programing relays, motors......

There is an old and well used terminology. Use that. Don't use home brewed terms, words.... It's like hiding the target in clouds of smoke.
Check with people working in the space or military field if precision in communication has any point! Have a look into aviation, how they communicate. Misunderstandings have no place there.

Here in forum a clear terminology leads to the solution much, much faster with less number of useless guesses passed to the OP.
