Trang 15.2 The "Heads-Up" Program Switcher
Only one program can be in front, or active, at a time
To make a different program active, you could click or double-click its icon (in the Dock, the Applications folder, or whatever) But the fastest method is to use the -Tab
keystroke (Figure 5-3)
Figure 5-3 Apple calls this row of open program icons a "heads-up display," named after the projected data screens on a Navy jet windshield that lets pilots avoid
having to look down at their instruments
You can use this feature in three different ways, which are well worth learning:
• If you keep the key pressed, each press of the Tab key highlights the Dock icon of another program, in left-to-right Dock order Release both keys when you reach the one you want Mac OS X brings the corresponding program to the front (To move backward through the open programs, press Shift- -Tab.)
• If you leave the key pressed, you can choose a program by clicking its icon with your mouse
• A single press of -Tab takes you to the program you used most recently, and another press returns you to the program you started in
Imagine that, for example, you're doing a lot of switching between two
programs—your Web browser and your email program, for example If you have five other programs open, you don't waste your time -Tabbing your way through all open programs just to "get back" to your Web browser
Tip: Here's a related keystroke, equally awesome If you press -tilde (the ~ key next
to the 1 key), you switch to the next window in the same program
