Change Mapped X Keysym

Getting there

In X Manager or X Manager for Domains, click Tools > Keyboard Maps.
Select an editable keyboard map (or click Clone to create a new editable map).
In the Keyboard Maps dialog box, click Map Key.
Select a key in the Explicitly Mapped Keys panel.
In the right panel, click Change Mapped X Keysym. (There are four buttons here; the Unshifted option is often the only one needed.)

NOTE:Administrators can also configure Keyboard Maps from the Domain Definitions tab.

There are four separate Change Mapped X Keysym buttons on the Map Key tab. In general, only one X Keysym (the one in the unshifted position) needs to be defined for any given key. However, a key can have different Keysyms associated with unshifted and shifted states.

Unshifted	The Keysym associated with this key when it is pressed by itself (without the Shift or AltGr keys). When the remaining X Keysyms are set to NoSymbol (the default), many X clients use this unshifted X Keysym regardless of the state of the Shift or AltGr keys. Use the additional mapping options only if you need a different behavior for shifted and unshifted states.
Shifted	The Keysym that is associated with the combination of the Shift key and this key.
Alt Gr	The Keysym that is associated with the combination of the Alternate Graphic key and this key. The Alternate Graphic key, also called Mode Switch or abbreviated AltGr, can be found to the right of the space key on most non-U.S. keyboards.
Shifted Alt Gr	The Keysym that is associated with the combination of the Shift key, the Alt Gr key,
