Extract Variable Dialog

Refactor | Extract Variable
Ctrl+Alt+V

Generally, this dialog is used to extract new variables. Depending on the language, there may be additional options, for example:

  • In JavaScript, you can select to extract a (global) variable or a constant. For JavaScript 1.7, JavaScript 1.8.5, ES5, and ES6, there is also an option of extracting a local variable.

  • In ActionScript, you can choose to extract a constant rather than a variable, and specify the variable type.
