VS 2008 Shortcut Key

There are many useful shortcut keys in VS 2008. In this post, I'll write some most useful key which are always used by myself.
Shift&Alt&Enter: Switch to Full-Screen mode;
Ctrl&Tab: Similar with Alt-Tab in Windows OS, it can switch windows that have been open currently in VS;
Ctrl&-: To navigate backward to previous place. For example, if you want to explore some class's definition, you will select "go to definition" item from context menu to navigate the definition detail. After you view it, in the most case, you want to back the previous place, so you can press this shortcut key. That's great and convenient for the developer. It seems like "Undo" feature;
Ctrl&Shift&-: To navigate forward to next place.
