1. Shortcuts
Eclipse provides keyboard shortcuts for the most common actions. Using shortcuts is usually preferable as you can perform actions much faster.
The master shortcut is CTRL+3. This shortcut opens the Quick Access dialog. In the quick access dialog, you can type the name of any command, preference, wizard, view, perspective, etc. You can also type only parts of the name and the dialog shows you possible matching elements.
