On my desktop computer, a mac using osx, the keys Command-+ and Command-- cause the current font on the screen to get larger (Cmd+) or smaller (Cmd-). Although I have a 24" monitor, I frequently use the keys to make the font large enough for my old tired eyes to be able to read comfortably. I recently purchased a netbook (12") to use mainly for travel. It uses Windows 7, and I cannot find the equivalent function, although it would be even more useful on my 12" screen as it is on my 24" screen. There is a "Magnifier" built it, but it goes in incremental steps that immediately make the font too large or too small. Does anyone know of an add-on that would give me a convenient screen font increase/decrease in Windows 7?
