This section describes how to run the UP.Simulator in HTTP direct mode.
Although you can use the UP.Simulator to view local files, you must have an Internet connection to access the Unwired Planet Developer Home Card and other HDML sites on the Internet.
The UP.Simulator connects to the Unwired Planet Developer Web site and displays the Developer Home card. The Developer Home card, shown in Figure 3-1, is the default start location and lets you navigate to some sample HDML and WML services.

If the UP.Simulator displays an error message, consult the UP.Simulator sections of the UP.SDK Tools and APIs Reference for troubleshooting instructions.
The default UP.Simulator keypad provides the following navigation keys.
FIGURE 3-2. Generic UP.Simulator navigation keys
By default, the first card the UP.Simulator displays is the Developer Home card. It contains a <SELECT> element with three items. To choose an item, click the 
and 
arrows to position the cursor (the 
symbol) on the item you want, then click the ACCEPT function key below the OK label (see Figure 3-1).
For example, to navigate to the WML Samples card, move the cursor to the third item and click the ACCEPT key. If a card contains more items than the UP.Simulator can display on one screen, click the 
arrow to scroll down and view the additional items.
Just as a Web browser has a Back command or button, all UP.Phones have a Back mechanism. As shown in Figure 3-2 above, the default UP.Simulator provides a BACK function key. The UP.Browser maintains a history of the cards you have accessed, allowing you to navigate backwards through the stack by clicking the BACK key. Unlike conventional Web browsers, UP.Phones do not have a Forward mechanism. To go forward, you must retrace your path by selecting the appropriate function keys.
Like conventional Web browsers, UP.Phones also have a Home mechanism. As shown in Figure 3-2 above, the default UP.Simulator provides a HOME function key. You can click on this key at any time to display your Home card. The default Home card for the UP.Simulator is:
http://updev.uplanet.com/dev/hdml/devhome3.hdml
If desired, you can specify a HDML deck you have created as your Home card. For more information, see Chapter 1of the UP.SDK Tools and APIs Reference.
On a real UP.Phone, users enter text by pressing keys on the keypad (see Figure 3-1). To enter text in the UP.Simulator, you can either use your computer keyboard or use the mouse to click on the keypad area of the screen. As shown in Figure 3-3, cards that allow text entry display the current text entry mode above the OPTIONS function key (for information about the different modes, see the UP.Browser User Handbook).
In ALPHA and SMART modes, each key enters different characters depending on the number of times you click it (or press it on a real UP.Phone). In ALPHA mode, the device cycles through the characters in the same order everytime. In SMART mode, the device cycles through the characters based on your previous entries--in other words, it tries to guess the character you want using a word-recognition algorithm.
The following table identifies the characters for each key in the generic UP.Simulator:
Figure 3-3 illustrates the process of entering the text "Send budget report!" using the ALPHA text entry mode.

SHIFT key that lets you switch between upper and lower case characters. To change case in the UP.Simulator, you must use the Shift key on your computer keyboard.
To navigate to a specific HDML deck, enter the URL in the Go field and press Enter (on your computer keyboard). You can also select previously visited locations from the Go drop down menu (see Figure 3-4).
