Creation of Keyboard in Photoshop 4 steps

This result does not create the entire keyboard, and only one key. The remaining you can create yourself.

1. We'll start by creating a new layer Layer / New / Layer and draw the shape of a key - it is a rectangle (slightly higher than broad) with rounded corners. Here we use a tool Rounded Rectangle Tool

2. To highlight the key result we use Layer / Layer Style / Bevel and Emboss  with Depth  1, 000%,  Size , depending on the size of the drawing,  Opacity with Highlight Mode and Shadow Mode 65%:

3. Highlight the center of the drawing and fill it using the Reflected Gradient Tool  key color (background) and a slightly darker shade (foreground)

4. On a new layer add a black symbol (eg, the selected letter of the alphabet), the Opacity to 75% decrease in the Layer / Layer Style / Blending Options

And here is part of the entire keyboard:
