The Parameter Library Preferences dialog has three radio buttons across the top that control what the dialog edits. So far we have been using the dialog with the Edit Parameter Libraries radio button  selected, which means that we were just editing library settings for the current timing diagram.

Default Settings for new timing diagrams:

If we had selected the Edit Default Libraries radio button, then the libraries settings would have been saved in the ini file of the program. All new timing diagrams would automatically start with the default library settings. We will not demonstrate this in the tutorial.

View Parts mode:

Once the libraries are in the library list and have their specifications defined, you will be working with the dialog in the View Parts mode. You can select the radio button in the current dialog and continue with the tutorial. However, we want to demonstrate other ways to open the dialog, so close it for now.
