It may be hard to imagine, but once upon a time, pages on the World Wide Web didn’t have pictures, let alone animations, videos, and interactive graphics. All these elements were added through trial, error, debate, and debunk. Changes came when brave souls (like you) forged ahead and made things work with the tools at hand. If a commercial product worked well and was widely adopted, it became the de facto standard. Adobe’s PDF (portable document files) and Flash animation player are well-known examples. However, there’s always been a problem with proprietary and patent-encumbered technologies on the Internet. They’re like a toll road in the center of a major city. On the other hand, authorities and standards-writing groups have been known to create “standards” that few browser and web developers follow. Strictly structured XHTML pages fall into this category. The solution is to create standards for the Internet that are practical, usable, and don’t stifle creativity. Of course, that’s easier said than done.
As Adobe Edge continues to grow and change, we’ll be updating this book periodically. Your purchase of this book includes free updates to the ebook edition. To get your free ebook, go to http://shop.oreilly.com/product/0636920025658.do. Next to the Ebook buying option, click “Add to Cart.” Enter AE5MM in the Discount Code box; click Submit; click Checkout; and then follow the onscreen instructions.
If you don’t already have Adobe Edge on your computer, you may be wondering where to get it. At this writing, you couldn’t buy Edge from Amazon. That’s because at the moment, it’s free “preview” software from Adobe Labs. To download the program, go to http://labs.adobe.com/technologies/edge/. Click the Download Now button. If you don’t have an Adobe account, you’ll need to create one before you can download the software. You know the drill: name, email, password. Both the account and Edge are free. Adobe is not saying whether Edge, or a similar product, will continue to be free in the future. If you want more details on how to install Edge on your computer, check out Appendix A.
Despite the many improvements in software over the years, one feature has grown consistently worse: documentation. With the purchase of most software programs these days, you don’t get a single page of printed instructions. To learn about the hundreds of features in a program, you’re expected to use online electronic help, but with a Preview product like Adobe Edge, the help files are missing or incomplete.
But even if you’re comfortable reading a help screen in one window as you try to work in another, something is still missing. At times, the terse electronic help screens assume that you already understand the discussion at hand and hurriedly skip over important topics that require an in-depth presentation. In addition, you don’t always get an objective evaluation of the program’s features. (Engineers often add technically sophisticated features to a program because they can, not because you need them.) You shouldn’t have to waste your time learning features that don’t help you get your work done.
This book periodically recommends other books, covering topics that are too specialized or tangential for a manual about Edge. Careful readers may notice that not every one of these titles is published by Missing Manual-parent O’Reilly Media. While we’re happy to mention other Missing Manuals and books in the O’Reilly family, if there’s a great book out there that doesn’t happen to be published by O’Reilly, we’ll still let you know about it.
Adobe Edge Preview 5: The Missing Manual is designed to accommodate readers at every technical level. The primary discussions are written for advanced-beginner or intermediate computer users. But if you’re a first-timer, special sidebar articles called Up to Speed provide the introductory information you need to understand the topic at hand. If you’re an advanced user, on the other hand, keep your eye out for similar shaded boxes called Power Users’ Clinic. They offer more technical tips, tricks, and shortcuts for the experienced computer fan.
Edge works almost precisely the same in its Macintosh and Windows versions. Every button in every dialog box is exactly the same; the software response to every command is identical. In this book, the illustrations have been given even-handed treatment, rotating between the two operating systems where Edge is at home (Windows 7 and Mac OS X).
One of the biggest differences between the Mac and Windows versions is the keystrokes, because the Ctrl key in Windows is the equivalent of the ⌘ key on the Mac.
Whenever this book refers to a key combination, you’ll see the Windows keystroke listed first (with + symbols, as is customary in Windows documentation); the Macintosh keystroke follows in parentheses (with - symbols, in time-honored Mac fashion). In other words, you might read, “The keyboard shortcut for saving a file is Ctrl+S (⌘-S).”
Adobe Edge Preview 5: The Missing Manual is divided into three parts, each containing several chapters:
Part Two is all about animating the elements on the stage. You’ll learn advanced techniques for working efficiently in Edge. Animation is time-consuming work, but you can save lots of time by reusing and recycling your previous work. You’ll learn to manage and edit the Timeline and the transitions you create. The last chapter in this section is devoted to triggers and actions. You use these tools to automate your animation and give interactive control to your web pages.
Appendix A explains how to install Edge on both Windows and Mac computers. You’ll also find tips on where to look for discussions and additional Edge resources.
To use this book (and indeed to use Adobe Edge), you need to know a few basics. This book assumes that you’re familiar with a few terms and concepts:
Clicking. This book includes instructions that require you to use your computer’s mouse or trackpad. To click means to point your cursor (the arrow pointer) at something on the screen and then—without moving the cursor at all—press and release the left button on the mouse (or laptop trackpad). To right-click means the same thing, but pressing the right mouse button instead. (Usually, clicking selects an onscreen element or presses an onscreen button, whereas right-clicking typically reveals a shortcut menu, which lists some common tasks specific to whatever you’re right-clicking.) To double-click, of course, means to click twice in rapid succession, again without moving the pointer at all. And to drag means to move the cursor while holding down the (left) mouse button the entire time. To right-drag means to do the same thing but holding down the right mouse button.
When you’re told to Shift-click something, you click while pressing the Shift key. Related procedures, like Ctrl-clicking, work the same way—just click while pressing the corresponding key.
Menus. The menus are the words at the top of your screen: File, Edit, and so on. Click one to make a list of commands appear, as though they’re written on a window shade you’ve just pulled down. Some people click to open a menu and then release the mouse button; after reading the menu command choices, they click the command they want. Other people like to press the mouse button continuously as they click the menu title and drag down the list to the desired command; only then do they release the mouse button. Both methods work, so use whichever one you prefer.
Keyboard shortcuts. Nothing is faster than keeping your fingers on your keyboard to enter data, choose names, trigger commands, and so on—without losing time by grabbing the mouse, carefully positioning it, and then choosing a command or list entry. That’s why many people prefer to trigger commands by pressing combinations of keys on the keyboard. For example, in most word processors, you can press Ctrl+B to produce a boldface word. In this book, when you read an instruction like “Press Ctrl+L to insert a label,” start by pressing the Ctrl key; while it’s down, type the letter L; and then release both keys.
Throughout this book, and throughout the Missing Manual series, you’ll find sentences like this one: “Open the System Folder→Preferences→Remote Access folder.” That’s shorthand for a much longer instruction that directs you to open three nested folders in sequence, like this: “On your hard drive, you’ll find a folder called System Folder. Open that. Inside the System Folder window is a folder called Preferences; double-click it to open it. Inside that folder is yet another one called Remote Access. Double-click to open it, too.” Similarly, this kind of arrow shorthand helps to simplify the business of choosing commands in menus, as shown in Figure 1.
