Menu Items and the Toolbar
In this guide, Netica's menu items are indicated in bold, with arrows indicating choices or submenus, so File → Open means choose “Open” from the “File” menu of the main menu bar. Most menu items have a corresponding toolbar button, and from within Netica you can discover what the buttons do by resting the cursor on them briefly. For example, it will say “Open File”, when you rest it on the 
toolbar button.
Some of the toolbar buttons discussed in this guide may not appear on the toolbar when you first start Netica, so you may want to customize the toolbar.
Instead of using the menu or a toolbar button, you can often use a keyboard shortcut or a right-click menu, which have a few additional features not available from the overhead menu.
