Settings in Excel 2003
If you work with the same workbooks every day it will be helpful to open specific workbook files automatically whenever you start Excel. Any workbooks placed in the XLStart folder open automatically.
Like a common text, any comments can be formatted: Excel represents many allows you to customize most aspects of its appearance, including color, border, and margins.
Normally, cell comments are rectangular, but you can give a cell comment any shape you want:
Excel includes a variety of built-in formats that cover general, numeric, currency, percentage, exponential, date, time, and custom numeric formats. You can also design your own custom formats based on one of the built-in formats.
When a comment has been inserted in a cell, the little red triangle is being displayed to indicate a comment in a cell. This tip is how to hide/display this indicator.
Sheets can be grouped (connected) to facilitate creating or formatting two or more identical sheets. For example, you can create one sheet and copy it to two other sheets, or you can group three blank sheets and enter and format the content once-no subsequent copying required.
Having your 4 most recently used workbooks on the File menu (or Getting Started pane) is handy, but you may find it's not enough. You can increase the number shown up to 9.
Every workbook uses a palette of 56 colors, but you can change palette for the current workbook or even change the default colors for new workbooks.
You can greatly reduce data-entry problems in your workbooks by making Excel check entries before entering them in specific cells. To do so, you need to define restrictions and data-validation rules for those cells.
