Just right click a class file, form file, etc and choose Check Out. When you are done with it, Right click again and choose Check In. If you want to discard any changes you made, or didnt make any changes to a checked out file, right click and choose Undo Check Out which will keep Source safe from creating a new 'version' in its database.
Thanks for all the clarification, folks. I apprecaite it.
