Review
======

   Here is a brief summary of the various functions discussed in this
chapter.

`describe-function'
`describe-variable'
     Print the documentation for a function or variable.
     Conventionally bound to `C-h f' and `C-h v'.

`find-tag'
     Find the file containing the source for a function or variable and
     switch buffers to it, positioning point at the beginning of the
     item.  Conventionally bound to `M-.' (that's a period following the
     <META> key).

`save-excursion'
     Save the location of point and mark and restore their values after
     the arguments to `save-excursion' have been evaluated.  Also,
     remember the current buffer and return to it.

`push-mark'
     Set mark at a location and record the value of the previous mark
     on the mark ring.  The mark is a location in the buffer that will
     keep its relative position even if text is added to or removed
     from the buffer.

`goto-char'
     Set point to the location specified by the value of the argument,
     which can be a number, a marker,  or an expression that returns
     the number of a position, such as `(point-min)'.

`insert-buffer-substring'
     Copy a region of text from a buffer that is passed to the function
     as an argument and insert the region into the current buffer.

`mark-whole-buffer'
     Mark the whole buffer as a region.  Normally bound to `C-x h'.

`set-buffer'
     Switch the attention of Emacs to another buffer, but do not change
     the window being displayed.  Used when the program rather than a
     human is to work on a different buffer.

`get-buffer-create'
`get-buffer'
     Find a named buffer or create one if a buffer of that name does not
     exist.  The `get-buffer' function returns `nil' if the named
     buffer does not exist.
