On
my keyboard the default use is
plainly indicated by the six tiny squares (two rows of three squares). Obviously an abstraction of that ever so useless Launchpad.
Sounds like
someone needs to take a few days to become familiar with the capabilities of the OS.
I would particularly recommend a thorough review and
memorization of absolutely all keyboard shortcuts!
Of course, that should be done after every major update of the OS since the default settings sometimes change...
A day or two should be sufficient...
