In predefined fields and in some line item areas, you can save time by using the typeahead feature. If you already know what you want to enter, you can type the first several characters, then press Return or Tab. If you have typed in enough characters to uniquely identify what you're entering, the rest is filled in. If you haven't typed enough characters, a list of possible alternatives appears, with the closest match highlighted. Choose what you want to enter from the list.
When you're entering line items into windows like invoices and bills, the type-ahead feature is especially powerful. By typing just a few characters, you can enter a great deal of information about an item. For example, when you use type-ahead for an item in an invoice, the full item name is filled in along with item details like description and price.
