window, shown in Figure 5.24, to specify the tag-based languages against which the Validator should check, the specific problems that the Validator should check for, and the types of errors that the Validator should report. Figure 5.24. Use the Validator category to specify the tag-based languages against which the Validator should check. [View full size image]   Specifying a language that the Validator should check against is merely a matter a checking the box for the specific language in the list box. You can further customize options for a specific language by clicking the Options button just below the list box. Shown in Figure 5.25, the Validator Options dialog allows you to customize what the Validator checks for and ultimately what is displayed by the Validator in the Validation tab in the Results window. Figure 5.25. Define the types of errors the Validator checks for and how errors are displayed using the Validation Options dialog.           Setting Keyboard Shortcuts In line with configuring preferences is the ability to customize your own keyboard shortcut keys. Out-of-the-box, Dreamweaver maps most of its functionality to specific keyboard shortcut keys. Although some keyboard shortcuts may not seem all that familiar, most operations such as Ctrl+O/Option+O (Open), Ctrl+S/Option+S (Save), Ctrl+A/Option+A (Select All), Ctrl+C/Option+C (Copy), Ctrl+X/Option+X (Cut), and Ctrl+V/Option+V (Paste) are used in countless other programs and are easily recognizable in Dreamweaver. Other shortcuts, however, might seem new and unfamiliar, and might even be too long to remember. For this reason, Dreamweaver allows you to remap all keyboard shortcut keys to your liking and then print them to use as a reference while you develop. Mapping your own keyboard shortcuts is easy and begins with the Keyboard Shortcuts dialog, available by choosing Edit, Keyboard Shortcuts (see Figure 5.26). Figure 5.26. The Keyboard Shortcuts dialog allows you to create your own custom keyboard shortcut set. [View full size image]   The Keyboard Shortcuts dialog features a menu of various keyboard shortcut sets, buttons you can click to duplicate, rename, and delete sets, a list of keyboard shortcut keys based on menu options, and text boxes for changing existing keyboard shortcuts. A detailed list of functionality is given here: Current set: Out of the box, Dreamweaver comes with four different sets of keyboard shortcut keys including BBEdit, Dreamweaver MX2004, HomeSite, and Macromedia Standard. Dreamweaver defaults to Macromedia Standard but if you're accustomed to using shortcuts from the other programs, feel free to change this menu to the specific shortcut set you're comfortable with. Duplicate set: Dreamweaver doesn't allow you to remap "factory set" shortcut keys. Instead, you'll have to use this button to create a custom duplicate set.
