1. Shortcuts
1.1. Using shortcuts in Eclipse
Using shortcuts make a developer more productive. Eclipse provides keyboard shortcuts for the most common actions. Using shortcuts is usually preferable as you can perform actions much faster.
Eclipse supports of course the typical shortcuts, e.g. Ctrl+S for saving, Ctrl+C for copying the selected text or file and Ctrl+V for pasting the element currently in the clipboard.
1.2. Shortcuts on Mac OS
This description uses the shortcuts based on Windows and Linux. Mac OS uses the Cmd key frequently instead of the Ctrl key.
2. Quick Access
The Ctrl+3 shortcut allows you to perform all available actions in Eclipse. This shortcut puts the focus into the Quick Access (quick access) search box which allows you to execute any Eclipse command. For example you can open a Preference, a Wizard, a view and a Preference page.
You can also use QuickAccess to search for an opened editor by typing in the name of the resource which the editor shows.
