Hum... Select all (ctrl+A or Cmd+A) menu item selects everything in the context of the focused pane:
- if the furniture catalog as focus, Select all menu item is disabled,
- if the home furniture list has focus, Select all menu item will select all the furniture in the list (not the walls, rooms, dimensions and texts),
- if the plan or the 3D view has focus, Select all menu item will select everything in the plan, except the virtual visitor if you're in virtual visit mode.
