Eclipse Search Tips

A few search shortcuts:

• Ctrl+J - Incremental Find in the current file. Pressing again takes to next match
• Ctrl+O - Quick Outline for the current class. Quickly find a method/field by name
• Ctrl+T - Type Hierarchy. Works for classes and methods as well
• Ctrl+E - Find an open tab by name
• Ctrl+Alt+H - Call Hierarchy. Works for classes, methods and fields
• Ctrl+Shift+T - Open Type. Quickly find any type by name (Ctrl+Shift+R for resources) Camel case search works here. eg. type HM or HaMa to find HashMap

Search result highlighting in the editor:

1. Open Eclipse Preferences
2. Go to General->Editors->Text Editors->Annotations
3. Select Search Results from Annotation types
4. Mark all checkboxes and, optionally, choose color
