C-PgUp C-<SPC> C-PgDn M-x indent region or similar...

,----[ C-h f indent-region RET ]
| indent-region is an interactive compiled Lisp function in `indent'.
| It is bound to C-M-\.
| (indent-region START END &optional COLUMN)
| 
| Indent each nonblank line in the region.
| A numeric prefix argument specifies a column: indent each line to that column.
| 
| With no prefix argument, the command chooses one of these methods and
| indents all the lines with it:
| 
|   1) If `fill-prefix' is non-nil, insert `fill-prefix' at the
|      beginning of each line in the region that does not already begin
|      with it.
|   2) If `indent-region-function' is non-nil, call that function
|      to indent the region.
|   3) Indent each line as specified by the variable `indent-line-function'.
| 
| Called from a program, START and END specify the region to indent.
| If the third argument COLUMN is an integer, it specifies the
| column to indent to; if it is nil, use one of the three methods above.
