Test Keymap Behavior
How do I get to this dialog box?
In X Manager or X Manager for Domains
Click Tools > Keyboard Maps.
In the Keyboard Maps dialog box, click Troubleshooting.
Click the Test keymap behavior tab.
Administrators can also configure Keyboard Maps from the Domain Definitions tab.
This tab shows the X KeyPress and KeyRelease events that are sent to the X server in response to a key you press. The output is similar to that of the "xev" X client.
With this troubleshooting tool, you can confirm what event is being sent after mapping a key to an X Keysym.
