AutoCAD: Previous and Last Selection Set

AutoCAD's options for defining a selection set are extremely varied. Over time, we'll cover the majority of the lesser used or understood options in other topics, but today we'll focus on the 'Previous' and 'Last' selection methods. These two selection methods are incredibly useful for quick editing, especially since they're so simple. The 'Previous' selection method does exactly what it sounds like it would do. Choosing 'Previous' (type 'P <enter>') selects the last group of selected objects. Very useful for when you accidentally cancel a complicated selection set before you get to execute the command. The 'Last' selection method works slightly differently and is equally powerful. Choosing 'Last' (type 'L <enter>') selects the most recently drawn objects. Very useful for performing a modify action on that object you just created.
