The Preferences dialog is the dialog used to set user preferences. The Preferences dialog pages can be searched using the filter function. To filter by matching the page title, simply type the name of the page you are seeking and the available pages will be presented below. The filter also searches on keywords such as appearance and java. The history controls allow you to navigate through previously viewed pages. To step back or forward several pages at a time, click the drop down arrow and a list of the most recently viewed preference pages will appear.
The Preferences dialog can be found from the main workbench Window menu under Window > Preferences . Preference pages contributed by plug-ins will be found in this dialog.
