Extract Local Variable refactoring: (aka 'Introduce Explaining Variable' or
'Introduce Local Variable'.) To use it - select an expression used in one
your methods and choose 'Extract Local Variable' from the global 'Refactor'
menu. It will replace the expression with a reference to a newly declared
local variable. Optionally, it can replace all expressions matching the
selected one (within the method).
