Chapter 4. Programs and Documents > Keyboard Control - Pg. 114

How Documents Know Their Parents Reassigning a certain document--permanently After opening a TIFF file in, say, Photoshop for editing, you haven't really made any changes in the fabric of your Mac universe. The next time you double-click that file, it will open once again in Preview. If you wish this particular file would always open in Photoshop, the steps are slightly different. In fact, there are three different ways: · In the Choose an Application dialog box, turn on "Always Open With" (shown at bottom in Figure 4-13). · Start out with one of the techniques described above (FileÆOpen With, or Con- trol-click the file's icon and choose Open With)--but after you see the menu, press the Option key, too. Before your very eyes, the Open With command changes to say Always Open With. · Highlight the icon, and then choose FileÆGet Info. Open the "Open with" panel. Choose a new "parent" program's name from the pop-up menu. You'll see that the word "(default)" changes position, now tacking itself onto the name of the new program you've chosen. Tip: You can use this method to reassign the parenthood of a whole flock of selected icons at once. Once you've selected them, just hold the Option key, choose FileÆShow Inspector, open the "Open with" panel, and choose a new program from the pop-up menu. The message at the top of the window--"22 items," for example--reminds you that you're changing the whole batch at once. In fact, if you follow up by clicking Change All beneath the pop-up menu, you can reassign all TIFF files to open in Photoshop, not just the specific one or batch that you highlighted. Mac OS X asks you to confirm by clicking Continue or pressing Enter. From now on, double-clicking any similar kind of document (one that has the same file name extension) opens it in the newly selected program. Keyboard Control In Windows, of course, you can operate every menu in every program from the key- board--and every control in every dialog box--thanks to the power of the Alt key. Mac OS X offers full keyboard control, too. You can operate every control in every dialog box from the keyboard, including pop-up menus and checkboxes. And you can even redefine many of the built-in Mac OS X keystrokes, like Shift-c-3 to capture the screen as a graphic. In short, if you were a keyboard power-user in Windows, you'll feel right at home in Mac OS X. What follows are some of the ways you can control your Mac mouselessly. In the fol- lowing descriptions, you'll encounter the factory settings for the keystrokes that do the magic--but you can change these combos to anything you want in the System PreferencesÆKeyboard & MouseÆKeyboard Shortcuts tab. 114 switchingtothemac:themissingmanual
