Commands like SetCommandL or AddCommandToStackL have
the parameter aPosition, which is 3 for MSK (or CEikButtonGroupContainer::EmiddleSoftkeyPosition).
The following methods are also added for MSK (these can be used for other
softkeys too):
void DimCommandByPosition(TInt aPosition,TBool
aDimmed)=0;
TBool IsCommandDimmedByPosition(TInt aPosition)
const=0;
void MakeCommandVisibleByPosition(TInt aPosition,TBool
aVisible)=0;
TBool IsCommandVisibleByPosition(TInt aPosition)
const=0;
