Copy the control definitions for the controls whose positions you want to change from /usr/dt/appconfig/types/language/dtwm.fp to:
System-wide: /etc/dt/appconfig/types/language/name.fp
Personal: HomeDirectory/.dt/types/name.fp.
You must copy the entire control definition for each control to be moved.
Interchange the values of the POSITION_HINTS fields of the control definitions.
Save the file
Choose Restart Workspace Manager from the Workspace menu.
For example, the following definitions placed in a file /etc/dt/appconfig/types/C/MailHelp.fp interchange the positions of the Mail and Help Manager controls and lock these controls against personal changes.
CONTROL Mail { POSITION_HINTS 12 LOCKED True …the rest of the control definition }
CONTROL Help { POSITION_HINTS 5 LOCKED True …the rest of the control definition }
