If you come to WebStorm from an editor such as Notepad++ or Vim, you will quickly recognize that WebStorm is not a text editor. Sure, it has a slick text editor component with autocompletion, code folding, and more; but that's only part of the picture. You aren't supposed to pop a CSS file into WebStorm for a quick edit and be done with it: WebStorm is an IDE, and IDEs work with projects. So the first thing WebStorm wants you to do is to import your existing work as a project. If you maintain a live online site, that means downloading your work and creating an offline project.

The next logical step is to put the project under a version control system, as serious developers usually do. WebStorm is well integrated with several version control systems, including the ever-popular Git. Its VCS menu lets you check in revisions, browse the repository, create and apply patches, and more.
WebStorm helps you start new projects in style, too: It features built-in support for Twitter's Bootstrap framework, for HTML5 Boilerplate, and for a number of other frameworks. When I asked it to start a new project based on Bootstrap, it asked me what version of Bootstrap I want, and then it pulled the framework's official Git repository, unzipped it, and presented me with a project that was ready for me to start working on. I did have to wait a moment before I could browse in the project folder, because WebStorm was busy parsing it. Though this delay confused me at first, it was brief.
WebStorm's Settings dialog consists of a sprawling tree of categories and subcategories, many of which contain built-in trees of their own. It would have been bewildering if not for one great feature: live search. If you need to change something in the way WebStorm indents your code, simply type indent and the tree will narrow to include only categories related to indenting code. Click a category, and its entries will come up dimmed: Only the relevant setting appears at full brightness, so it instantly pops out at you.
Other parts of WebStorm are similarly keyboard-centric. Want to do something but aren't sure how to proceed? Press Ctrl-Shift-A and just start typing (for example, fold if you want to expand a fold using the keyboard). WebStorm will instantly search all of its menu items and settings for the substring you typed, and will let you execute the action that you need directly from that dialog, so there's no need to hunt through menus. It will even show you associated keyboard shortcuts, so you won't have to use Ctrl-Shift-A the next time (Ctrl-Numpad-+ expands the current code fold). Webstorm's autocompletion support is excellent as well, right down to converting CSS colour names to hexadecimal numbers.
