What is this component in an Airbus cockpit? I have noticed that on a lot (all?) Airbus cockpits, there are these "things" (for lack of a better term) under the panel.

I have highlighted them in this picture of an A340 cockpit:



What are they?
Since Airbus planes use a sidestick instead of the traditional center yoke, they use the space where the yoke would be to include a fold out table instead. You can see a laptop on one here. The A380 version also has a keyboard. This is used to interface with the onboard systems and input information.
