The ZDesktop not synchronize properly with the keyboard shortcuts to Webmail. If the shortcuts are created in ZDesktop they work only until they are synchronized with the server.
I created four keyboard shortcuts in Webmail as the image below

After log off and log back in to Webmail they appear as the image below

And after enabling ZDesktop, in which there was no keyboard shortcut set, the keyboard shortcuts were lost in the Webmail

Entries for the shortcuts were maintained, however, lost the names of tags and shortcuts.
