Sort Lines in Vim

You are working in Vim. You come across this code:

gem "clearance", "1.0.0.rc4"
gem "neat"
gem "stripe"
gem "pg"
gem "thin"
gem "rails", "3.2.11"
gem "bourbon"
gem "simple_form"
gem "strong_parameters"

You want to sort the list alphabetically. You select the lines visually:

Shift+v

You invoke the sort function:

:sort

You rejoice:

gem "bourbon"
gem "clearance", "1.0.0.rc4"
gem "neat"
gem "pg"
gem "rails", "3.2.11"
gem "simple_form"
gem "stripe"
gem "strong_parameters"
gem "thin"

You dig deeper:
