Adding comments

Add comments and reminders to individual cells in Excel. Click the cell where you want to put a comment and select Comment from the Insert menu. Enter your comment and click outside the comment box when finished. Cells with comments are denoted by a small, red triangle located in the upper right-hand corner of the cell. To read a cell's comment, move the mouse over the cell. To keep a comment visible, right-click the cell and select Show Comment from the pop-up menu. To hide the comment, right-click the cell and select Hide Comment from the pop-up menu.

StarOffice and OpenOffice.org use a similar system except that they use the term "Note" instead of "Comment" on the Insert menu and "Show Note" on the pop-up menu.
