Excel 2003
How to enter a new line on a cell
If you have lengthy text in a cell, you can force Excel to display it in multiple lines within the cell.
How to use keyboard to navigate in the spreadsheet
To move around the worksheet with your keyboard, use the key combinations:
Recalculating the worksheet
If you are working with huge workbooks that contain a very large number of formulas, functions, and data,
you can turn off the automatic recalculation.
Locking cells in a spreadsheet
Sometimes you might want to lock cells in your Excel spreadsheet that contain formulas and functions or
data. Thus, the person doing the data entry will not accidentally overwrite or delete the spreadsheet
formulas and functions or your data.
How to protect spreadsheets
You can significantly reduce the number of errors in data entry in Excel by protecting changes of specific
spreadsheets (worksheets) and cells.
Protecting workbook elements
Much like as you can protect elements of each Excel spreadsheet (see Protecting spreadsheet elements for
more details), you can protect structure of the sheets in the workbook, prohibiting renaming, moving and
other operations.
Share workbook and track changes
With Excel built-in tools you can easily work together on workbooks and monitor who, when and what changes
made. E.g., track project status and tasks.
Protecting spreadsheet elements
Working with large and complex Excel workbooks, especially when entering large amounts of data, no one is
protected from accidental changes in formulas, formats and other spreadsheet elements. But you can protect
yourself from too much work on finding and eliminating such errors by protecting the individual spreadsheet
elements.
Allow specific users to edit ranges in a protected spreadsheet
Excel offers you an ability to assign user-level permissions to different areas on a protected spreadsheet.
You can specify which users can edit a particular range while the spreadsheet is protected. As an option,
you can require a password to make changes.
Combining text and formatted values
The Excel TEXT function enables you to specify numbers and date format.
