I'm not sure if it's a mild case of CDO ( surely the letters ODC aren't in order ! ), but I was struggling to align some elements in a Business Process Definition.
Thus, I was looking for the zoom controls, and stumbled across Key Assis
This is, of course, a feature of Eclipse, and I've written about similar capabilities in IBM Notes
Anyway, here's the Key Assist panes for Process Designer ( I'm using 8.5.7 on Windows 7 )
For the record, the zoom controls are right there :-)
