Yes. You can use the Flyout Menu from the Actions Pallet (triangle in the upper right corner). You should NOT be in button mode, and when you save them, the Save option will only be active when you highight an action set.
Another way is to find the Actions Pallet.PSP and copy that over to the other machine. This will duplicate the ENTIRE actions pallet and all actions. Mind you, if you choose this method, you should still save out individual sets in case of a crash or if you have to reset your preferences, but it’s a great way to duplicate the entire pallet.
The actions pallet psp file is found in Windows\Application Data\Adobe\Photoshop\7.0\Photoshop Settings.
Peace,
