There are many options for selecting objects. All of these options are generally available for every command that displays a "Select objects:" prompt. You can type "?" (a question mark) at the prompt to see all the options. A complete description of each option is given in the Autocad help for the "SELECT" command.
The highlights:
Type WP to use a "Window Polygon" to select. This lets you draw an irregularly-shaped area, and all objects that are completely inside the polygon are selected.
Type CP to use a "Crossing Polygon" to select. Similar to a Window Polygon, except it also selects all items that are crossing the edge of the polygon, even if they aren't completely contained inside the polygon.
Type F to use a "Fence" to select. You are prompted to draw a polyline, and all items touching the polyline are selected.
Also note that you can type R to switch to "Remove" mode. This works kind of like holding down the SHIFT key, except it lets you use the other options to remove items from a selection set. So, for example, you can select all objects in an entire area. Then hit "R" to switch to "Remove" mode, and then use a Fence selection to remove certain items from your selection set. Typing A will return you to "Add" mode.
