A few new keyboard tricks has been implemented in windows Vista, and some more were modified compared to their XP equivalents. for example:
open a folder containing pictures, videos, or just any files. hold Ctrl and roll the mouse wheel. This will change the thumbnails size.
hold Alt while going forward or backward from any folder. This will hide the file-names from appearing. this is perfect for folders containing Photos.
If you have vista Aero. try winkey-tab. this will start switch between active windows in 3D style.
You can always try other keyboard shortcuts from windows XP because most of them still work.
One more thing if you use the “Windows Task Manager” a lot, you can directly activate it by pressing Ctrl-Shift-Esc without having to jump through the logon window.
