Check all/Uncheck all (PCB Layout object selection)

[T.Nakamura]

I'm not sure if it has been already requested, but if there's Check All/Uncheck All for the object selection, it would be very helpful.
(Is there any way to do that?)
Sometimes I would like to select only one object (Like Board outline) to avoid unintentional operation for other objects, but it is really painful to check/uncheck all the other every time.

It seems Check All/Uncheck All options have been requested. Anyway, thank you for the feature request, we will consider it.
