Use SELECT and pick the first part. ESCape a couple of times to clear that selection, which will then be the "Previous" selection. Then start whatever command you intend, type ALL to select everything, then type R for Remove and P for Previous to take the previous selection out of the current [everything] selection, so you're left with the inverse selection -- ENTER to finalize that and proceed with the command.

Possibly you can use the Group command to help.

Make a Group of objects that you have currently selected. Then SelectAll and Unselect your Group. Then Ungroup. Easy.
