Muchos web designers regularly use a large number of programming languages, with all its codes and characters, so many that it is impossible to remember them all, it is enough that they remember the ones they use the most.
In Dzinepress they have made a splendid compilation of 50 "chops" with web programming codes for web developers and graphic designers.
These lists are great for not having to memorize all that information from the programming languages or to get hold of them when you get stuck with the keyboard shortcuts to save time.
So here I leave you the link to the web where you can download these chops of languages like HTML, JavaScript, Python, Ruby-on-Rails, Ajax, CSS3, HTML5, XHTML, XML, MooTools, ASP, VB Script, Prototype, MySQL, jQuery, htaccess, mod_rewrite, 3D Max, Cinema 4D R8, PHP and CSS.
In addition, there are also a few chops with keyboard shortcuts for graphic design programs like Adobe Photoshop and Illustrator.
