=head1 OVERVIEW
This is B<Chapter 10 of 10> for the Catalyst tutorial.
=item *
-":0,$s/^ "
+C<":0,$s/^ ">
Removes four leading spaces from the entire file (from the first line,
C<0>, to the last line, C<$>).
=item *
-"%s/^ "
+C<"%s/^ ">
A shortcut for the previous item (C<%> specifies the entire file; so
this removes four leading spaces from every line).
=item *
-":.,$s/^ "
+C<":.,$s/^ ">
Removes the first four spaces from the line the cursor is on at the time
the regex command is executed (".") to the last line of the file.
=item *
-":.,44s/^ "
+C<":.,44s/^ ">
Removes four leading space from the current line through line 44
(obviously adjust the C<44> to the appropriate value in your example).
You can limit the replacement operation by selecting text first (depending
on your version of Emacs, you can either use the mouse or experiment with
commands such as C<C-SPC> to set the mark at the cursor location and
-C<C-E<lt>> and C<C-E<gt>> to set the mark at the beginning and end of the
+C<< C-< >> and C<< C-> >> to set the mark at the beginning and end of the
file respectively.
-Also, Stefan Kangas sent in the following tip about an alternate
-approach using the command C<indent-region> to redo the indentation
-for the currently selected region (adhering to indent rules in the
-current major mode). You can run the command by typing M-x
-indent-region or pressing the default keybinding C-M-\ in cperl-mode.
