Q: I don't have one of those multimedia keyboards with volume control, or those media control mice. I still want to control my volume in a hurry, preferably with my mouse. Any suggestions?
A: Try VolumeTouch, a freebie app. It installs as a tray app. Once installed, hold Ctrl-Shift, then use your mouse scroll wheels (or vertical / horizontal position if you don't have a scroll wheel) to adjust volume.

Q:Do you know where I can get apps that will run straight off a USB flash drive without installation?
A: Best index of such apps is at http://portableapps.com , including OpenOffice Writer, CoolPlayer+, and many more.
