Question

where should we keep the keyboard​

Answer 1

Your keyboard should be at a height that allows your elbows to be bent about 90 degrees and close to your sides. Many keyboards and keyboard trays have wrist supports to help keep your wrists in a neutral, almost straight position. But wrist pads are just there for brief rests.

Answer 2

In the proper position, the keyboard should be placed just above the level of your lap. This is lower than most people normally place their keyboard, but lets our arms tilt downward while using the keyboard, leaving our elbows at a comfortable "open" angle.
