9 Selecting and Moving Text

Many Emacs commands operate on an arbitrary contiguous part of the current buffer. You can select some part of the buffer and edit only that part of the buffer. This selected buffer is called a region. You can select text in two ways:

• You use special keys to select text by defining a region between the cursor and the mark (which you set).
• If you are running SXEmacs under X, you can also select text with the mouse.
