My top 5 MS Excel shortcut keys

There are so many shortcut keys in all the MS Office applications, and I use many of them without much thought as they have become second nature. These are my top 5 and have been ranked such due to their popularity with just about everyone I've ever showed them to.  Hope you find them useful too
Insert the current date	Ctrl ;	This inserts the date as a fixed value which means it will not update daily.  If you require the date to update automatically use =Today() instead
Insert rows/columns	Ctrl +	New columns/rows will be inserted before the column/row that is currently selected.
Create a chart using selected data	F11	Creates a new chart on a separate sheet
Navigate through data	Ctrl {arrow keys}	Jumps you from the active cell to the next or last cell containing data in the dirction of the arrow pressed.   If nothing is found, you will be moved to the end of the spreadsheet.
Quick highlight	Ctrl Shift {arrow keys}	As above, but highlights rather than just moving through data
