Log
Note:
In this "Basic Interface" any change in the selection of a pulldown menu automatically triggers an action (one-step mechanism).
View and selection are coupled in the structure specific controls (e.g. "Hetero","PROSITE") .
Note:
In this "Advanced Interface" any change in the selection of a pulldown menu only sets the target for the corresponding control buttons (two-step mechanism).
View and selection are set independently in the structure specific controls (e.g. "Hetero","PROSITE") .
