Hello NightDuty,

You could view all of the shortcuts which could be set in the following enum 'System.Windows.Forms.Shortcut'. Please take a look at: http://msdn.microsoft.com/en-us/library/system.windows.forms.shortcut.aspx.

ultraToolbarsManager1.Ribbon.Tabs[0].Groups[0].Tools[0].SharedProps.Shortcut = Shortcut.//whatever you want.

Please feel free to let me know if I misunderstood you or if you have any other questions.
