Under the Menu bar by default are three toolbars: the Standard toolbar, the Formatting toolbar, and the Formula bar.
The icons on these toolbars provide a wide range of common commands and functions. The toolbars can be modified, as discussed in Chapter 14 (Customizing OpenOffice.org).
Placing the mouse pointer over any of the icons displays a small box, called a tooltip. It gives a brief explanation of the icon’s function. For a more detailed explanation, select Help > What's This? and hover the mouse pointer over the icon. Tips and extended tips can now be turned on or off from Tools > Options > OpenOffice.org > General.
In the Formatting toolbar, the two rectangular areas on the left are the Font Name and Font Size menus. If there is something in these boxes, they show the current setting for the selected area.
Font name and font size
Click the little button with an inverted triangle to the right of the box to open a menu. From the Font Name and Font Size menus, you can change the font and its size in selected cells.
