The options associated with that category are displayed from which you can choose. Click and drag your mouse pointer to the menu option that you want to use and release. If you click on a menu that brings up a second menu or submenu, click and drag to the option desired. Sometimes you will pull down a menu that you don't really want. If this happens, click somewhere outside of the menu and you will close the pull-down menu without executing any unwanted commands.
Buttons Buttons make choosing menu options easier.
Instead of clicking and dragging through successive menus, you can just click on a representative icon. When your mouse pointer is on a button, a brief description of the button's function is displayed. Click the button once to perform the desired function or to format highlighted text. To turn the feature off, click the button once again. You can customize your buttons to display the ones you use most frequently.
