# Fiddle-IT > A tiny & simple userscript for creating fiddles in seconds. > > Very handy for answering questions when you want to test the OP's code --- ## Usage Select some code on the page, then press one of the following: * HTML - <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>H</kbd> * CSS - <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>C</kbd> * JS - <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>J</kbd> To add the jQuery library to your fiddle, press the following: * jQuery - <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>1</kbd> To activate your fiddle, press <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>F</kbd> ## Customizing To add new libraries, you can do this inside the `keyup` event listener if( event.keyCode === yourNewNumber ) return setLibrary('mootools', '1.0'); Check the libraries in JSFiddle for more info. ## Demo I made a quick demo video for you to watch: [YouTube demo](https://www.youtube.com/watch?v=TE5oHYNYXJQ) (make sure you have annotations on). --- ## Download # [User Script][1] # [GitHub][1] [1]: https://github.com/connorGFX/Fiddle-IT/raw/master/fiddle-it.user.js [2]: https://github.com/connorGFX/Fiddle-IT
