The notation can be confusing (it's alien, really). But it's worth learning. I thought I knew it pretty well, but some of the stuff I see here is really awesome.
To answer your questions, I don't know what :g//d does. g generally means "global" and d "delete", but in the VI I'm using it doesn't work.
You already know what \(...\) means, you said.
s/.*//g means replace everything with nothing (where /.*/ means everything and // means nothing).

PPIx::EditorTools::RenameVariable(3pm) User Contributed Perl Documentation PPIx::EditorTools::RenameVariable(3pm)NAME
PPIx::EditorTools::RenameVariable - Lexically replace a variable name in Perl code
SYNOPSIS
my $munged = PPIx::EditorTools::RenameVariable->new->rename(
code => $code,
line => 15,
column => 13,
replacement => 'stuff',
);
my $code_as_strig = $munged->code;
my $code_as_ppi = $munged->ppi;
my $location = $munged->element->location;
DESCRIPTION
This module will lexically replace a variable name.
METHODS
new()
Constructor. Generally shouldn't be called with any arguments.
rename( ppi => PPI::Document $ppi, line => Int, column => Int, replacement => Str ) =item rename( code => Str $code, line => Int, column =>
Int, replacement => Str ) =item rename( code => Str $code, line => Int, column => Int, to_camel_case => Bool, [ucfirst => Bool] ) =item
rename( code => Str $code, line => Int, column => Int, from_camel_case => Bool, [ucfirst => Bool] )
Accepts either a "PPI::Document" to process or a string containing the code (which will be converted into a "PPI::Document") to
process. Renames the variable found at line, column with that supplied in the "replacement" parameter and returns a
"PPIx::EditorTools::ReturnObject" with the new code available via the "ppi" or "code" accessors, as a "PPI::Document" or "string",
respectively. The "PPI::Token" found at line, column is available via the "element" accessor.
Instead of specifying an explicit replacement variable name, you may choose to use the "to_camel_case" or "from_camel_case" options
that automatically convert to/from camelCase. In that mode, the "ucfirst" option will force uppercasing of the first letter.
You can not specify a replacement name and use the "to/from_camel_case" options.
Croaks with a "no token" exception if no token is found at the location. Croaks with a "no declaration" exception if unable to find
the declaration.
