Collapsing lists in folder/category view

This normally achieved by ctrl + *, but with my new small laptop the '*'key is only upper case.  I find that ctrl + shift + * doest not work.  Is there an alternative?

This is all managed by Windows, not IMatch.
Check the Windows help system for information about keyboard shortcuts for tree controls on your platform/ device. Maybe your vendor has assigned a special key for this purpose.
