Hand Held Products 7400/7450 用户手册

There are some keyboard functions and special characters not defined on the Dolphin 7400 and 7450 keyboards. See the charts 
in Appendix A for the key combinations used to access these functions and special characters on your terminal.

The Dolphin 7400/7450 terminals have a mouse utility to simplify navigating around the screen, especially for non-touchscreen 
equipped terminals.* 

*Exit the mouse utility prior to adjusting the contrast.

To activate the mouse utility at any time in any window, double-tap the blue modifier key and the mouse pointer will appear in 
the middle of the screen as shown in the screen shot below. To deactivate the mouse, double-tap the blue modifier key again 
and the mouse pointer will disappear.

Use the cursor keys to navigate around the screen. For a left mouse click, press either one of the ENT keys. Use a left mouse 
click to select an item or launch a program.

 

For a right mouse click, use the TAB key . When you use a right mouse click, a menu 

of items pops up and tells you what actions you can perform, and shows you shortcuts. To open files or applications with a double 
click, tap the ENT key twice in rapid succession. 

In mouse mode, you can also scroll the active window for dialog boxes that are not formatted for the 1/4 VGA display. Move the 
cursor to one of the four screen edges and continue to hold down the arrow key to initiate the scrolling feature.

To adjust the double-click speed for the mouse utility, go to Control Panel>Settings>Stylus. Follow the directions on the Double-
Tap tab to adjust the settings. Note: The Double-Tap setting for the stylus also applies to the mouse.
