This is the easy-to-read keyboard with high-contrast keys and enlarged print. The bright yellow keys are labeled in black, san serif type, the same high-visibility color scheme used for highway warning signs. The 43-point characters (about 9/16" tall) are heat transferred to the keys, after which a UV coating is applied for lasting durability. The 103-key layout is the same as that on a standard keyboard, with 12 function keys along the top row, plus nine buttons for common multimedia and browser commands. The USB keyboard is rated for 10 million keystrokes, ensuring years of trouble-free typing. Flip-up legs angle the keyboard for comfortable typing. For Windows 7, Vista, and XP. 1" H x 17 1/2" W x 6 3/4" D. (1 1/2 lbs.)
