Here is a really cool utility (portable app), called Win7se, that you simply download, run and then place your mouse pointer in any of the four corners (hotspots) of your screen for the magic to happen.
For example, if I place my mouse pointer in the top left of the screen, the Windows 7 Alt-Tab Switcher will come up allowing me to toggle between any of the multiple apps I have running. If I place the pointer in the top right corner of the screen my desktop and desktop icons will (overlay) appear on top of whatever I am working on allowing me to start another application. If I place the mouse pointer in the bottom left corner of the screen, the monitor display will go to sleep. If I place the pointer in the bottom right corner of the screen my screensaver will start.
Each of these four corner hotspots are configurable (to a certain degree), by simply right mouse clicking the Win7se icon in the system tray and selecting “Settings”. At this point you can select how you want each hotspot to respond. Win7se, I am finding, is a very clever and handy tool.
