Build a presentation controlled by keyboard

Hi, i need present a project... this project display two meters. Decibels and intensity, but this data input must be controlled by keyboard. So, we dont need meter decibels really, Only i need control this graphics by keyboard as I show in the picture. With A,S i need controlling the dB, with K,L i need controlling the intensity. In the middle must be appear de average (all data is in porcentage) between intensity and db. You can use any application or framework or flash, as you think is better. I found this reference, but if you have another similar cool presentation, i deal whit it. Only remember that i need controll them.
