Cant assign CTRL key to "move with window within wall" left or right

[zzecool]

Ubuntu version : Precice Pangolin 12.04

In the desktop wall plugin

using
compiz 1:0.9.6+bzr20110929-0ubuntu8
compiz-plugins-main 1:0.9.6-0ubuntu4.2
compizconfig-settings-manager 0.9.5.92-0ubuntu2

If you try to assign the CTRL key or a combination with CTRL key like " <Control><alt> " to move left with window or move right with window it fails. Actually if you grab the CTRL button instead of grab <Control> it grabs <primary> .

I dont even know what the "primary" button suppose to be but even if you try to manual type <Control> then it rejects the entry and disables the feature.

Ok i found that the problem is Based on the Compizconfig-settings-manager because you can successfully assign the CTRL key using the gconf-editor tool .

I hope for a fix because this one effects the default install , even for a user that doesnt use the Compizconfig-settings-manager , because this is available as a keyboard shortcut ( Navigation ) on the keyboard settings as "Move window one workspace left ( or right ) ", and it doesnt work if you try to assign CTRL key there too but without give you the <primary> entry "error" instead...
