I have a Mac OSX desktop computer and a Windows 7 netbook. OSX has a feature that allows easy zoom using the keys cmd+ and cmd-. Being an older user with less-than-perfect eyesight, I love that feature and use it all the time. Things seem harder to enlarge in Windows 7, and it's important enought to me to want to set up some fast method for accomplishing the same thing I can do with cmd+ and cmd-. But I haven't been able to figure it out. Do you have any suggestions, and thanks in advance?
