Browser controls inaccessible

While using ChessCube, it's impossible to open a new tab (Ctrl+T), switch tabs (Ctrl+Tab or Ctrl+2), access the address bar (Ctrl+L), etc. This is a problem, especially when ChessCube is the only tab open. Can you please let keyboard shortcuts remain accessible while using the interface?

as you can see from this screenshot, it means I'm stuck and can't go anywhere else
