ESC to close Windows

[Jörgen]

Hi, just a little suggestion to make live (planning, viewing etc.) easier.

If you are in someone´s route with pictures and want to view this pictures, is it possible to close these windows (or the picture) with the ESC button?

I think it is quicker and easier then clicking on the close "x" or on "close Window".

This should be an easy one for the devs.
