## Key-Controlled Help Navigation

Although a mouse is the most convenient tool for navigating within the R&S ZVA Help system, it is possible to access all active and interactive elements by means of the front panel keys. The following sections give an overview.

Entering characters

### To access the tabs in the navigation pane
...

| Press the MENU key in the SUPPORT keypad to activate the menu bar.
| Press the Cursor Right key in the NAVIGATION keypad twice to move the cursor to the View menu.
| Press OK ENTER in the NAVIGATION keypad to expand the menu.
| Press the Cursor Down key in the NAVIGATION keypad repeatedly until you reach the desired tab. The tab is activated and the cursor is automatically moved into the tab.

### To access the topic pane
and its active elements...

By default, one of the tabs in the navigation pane is active when the Help is opened. To switch over to the topic pane (and back), use the Switch Pane menu command.

| Press the MENU key in the SUPPORT keypad to activate the menu bar.
| Press the Cursor Right key in the NAVIGATION keypad three times to move the cursor to the Switch Pane! menu.
| Press OK ENTER in the NAVIGATION keypad to switch over to the topic pane.

### To control active elements...

The navigation and topic panes of the Help system contain various types of active elements
.

- An expandable tree view represents the table of Contents (TOC).

- The Index and Glossary tabs contain alphabetical list of keywords.

- The Index and Search tabs contain input fields to specify a keyword to find.

- Various types of links within the topics open text popups, expand additional text and initiate a jump to another topic.

The list below only contains the most important control keys for Help navigation. Some setup keys provide additional shortcuts. While the Help is open, all front panel controls do not act on the NWA application, so there is no risk of corrupting the measurement by inadvertently hitting keys.

- Scrolling up and down

  | Press the Cursor Up and Cursor Down keys in the NAVIGATION keypad or turn the rotary knob to scroll up and down in the table of contents, in a list of keywords or in the topic text.

- Activating links

  | Press OK ENTER in the NAVIGATION or DATA ENTRY keypads or the rotary knob to expand/compress chapters in the table of contents and activate links. Links can start from books in the table of contents, buttons, index keywords, search lists or hot (colored) text in topics.

- Handling TOC hierarchies

  | Use the Cursor Right key in the NAVIGATION keypad to expand the TOC tree. Use the Cursor Right and Cursor Left keys to move one TOC level down or up.

- Accessing active elements

  | Use the Left Field or Right Field keys in the NAVIGATION keypad to switch between several active elements in the tabs (e.g. the input field, list of keywords and Display button in the Index tab) or different links in the topic.

- Entering characters

  ... | The keys in the DATA ENTRY field allow you to enter the numeric characters 0 to 9 and the letters G, M and K. To enter other characters, a mouse or external keyboard is required. With a mouse but no external keyboard installed, you can call up Windows XP's On-Screen Keyboard, and simply click the characters needed.
