Best Shortcut Keys In Microsoft Excel

Windows - On either side of the spacebar, outside the Alt key, is a key with the Windows logo. Holding the Windows key down and pressing another key will initiate quite a few actions. Some of the more common are listed in the table below:
+ F to display Find: All Files
+ F1 to display Help
+ R to display the Run command
+ M to minimize or restore all windows
+ E to display Windows Explorer
+ Break to display System Properties
+ Tab to cycle through buttons on the task bar
Shift + + M to undo minimize all windows
to display the Start menu
and then press U to display the Turn Off Computer menu, press U again (on laptops) or press S (on desktops) to Turn Off the computer. + D to quickly get to your Desktop [Thanks Charlotte!] If your computer has XP installed and you want to lock your computer when you walk away from it use + L . OK, I won't leave you hanging. Your Windows password will unlock your computer.
Ctrl + S to save the current document Ctrl + U to add/remove Underline formatting Ctrl + 9 to hide rows in MS Excel (add Shift to the sequence to unhide .)
Ctrl + Tab allows movement from one open window to the next in an application with more than one open window.
Ctrl + F4 to close a window in an application without closing the application.
Ctrl + Enter while in Internet Explorer - Enter only the domain name then depress Ctrl before striking Enter/Return. IE automatically fills in the complete URL for a .com address. Ctrl + A to display the arrow in a PowerPoint show Ctrl + - (Hyphen) to bring up the Delete dialog box in MS Excel Ctrl + C + C to open the clipboard (Alex Khouri told me about this one. Thanks Alex!) Ctrl + 0 to hide columns in MS Excel (add Shift to the sequence to unhide.)
Ctrl + arrow (in Excel) - In a large worksheet this combination allows you to quickly move left, right, up, or down. Starting from cell A1, depressing Ctrl and pressing the right arrow moves to the cell in row 1 adjacent to the first empty cell. Ever wonder how many rows are in a worksheet? On a blank worksheet hold down the Ctrl key and press the down arrow. (Thanks to George Held for this shortcut)
