The Module Title Bar
The module title bar (Figure 5-5) is located between the schematic viewer tool bar and the schematic viewer display and shows the module name, the instance name, and the associated hierarchy of the current module. A history of previously selected modules is maintained and can be displayed by clicking on the scroll down arrow and selecting the module.
The columns on the far right indicate the page sequence of the schematic. If the paging is not split into multiple pages, the last column will contain the term “unspl” to indicate that a multipage schematic is compacted onto a single page. There are two ways to split a multipage schematic: View–Schematic Preferences–Paging–Page Size and Generate all Pages in the Commands Pop-Up Menu.

Searching for an Object
The search dialog (shown in Figure 5-6) allows you to search for a specific instance, net, port, bus, or module in the schematic or a list of all instances, nets, ports, bus, or modules in the schematic. You may have multiple search windows: one search window per schematic window.
The results of the search are displayed in the dialog box. A single left mouse click simply highlights the object. A double left mouse click displays and centers the selected object.
