When you double-click on the name of a style in the Styles and Formatting window, a Style dialog similar to the one shown below opens.
The Style dialog has several tabs. The Organizer tab, shown below for cell styles, is found in all components of OOo). It provides basic information about the style. The Organizer tab for page styles is similar to the one shown for cell styles.
Organizer tab of Cell Style dialog.
This is the style’s name. You cannot change the name of a built-in style, but you can change the name of a custom style.
This option is only available for cell styles; page styles cannot be linked. If you link cell styles, then when you change the base style (for example, by changing the font from Times to Helvetica), all the linked styles will change as well. Sometimes this is exactly what you want; other times you do not want the changes to apply to all the linked styles. It pays to plan ahead.
For example, you can make a new style called red, in which the only change you want to make is for the cell text to be red. In order to make sure that the rest of the text characteristics are the same as the default style, you can link red with default. Then, any changes you make to default will be automatically applied to red.
In Calc, the only option in this drop-down box is Custom styles.
