2.2. Useful Hints

Many Eclipse users learn useful tricks and troubleshooting techniques throughout their experience with the Eclipse user interface. This section highlights some of the more useful hints that users new to Eclipse may be interested in learning. The Tips and Tricks section of the Workbench User Guide contains a more extensive list of Eclipse tips.

2.2.1. The quick access menu

One of the most useful Eclipse tips is to use the quick access menu. Typing a word in the quick access menu will present a list of Views, Commands, Help files and other actions related to that word. To open this menu, press Ctrl+3.

In Figure 2.10, “Quick Access Menu”, clicking Views > Project Explorer will select the Project Explorer window. Clicking any item from the Commands, Menus, New, or Preferences categories to run the selected item. This is similar to navigating to or clicking the respective menu options or taskbar icons. You can also navigate through the quick access menu using the arrow keys.
It is also possible to view a complete list of all keyboard shortcut commands; to do so, press Shift+Ctrl+L.

To customize the current perspective, navigate to Window > Customize Perspective. This will opens the Customize Perspective menu, allowing the visible tool bars, main menu itmes, command groups, and short cuts to be configured.
The location of each view within the workbench can be customized by clicking on a view's title and dragging it to a desired location.

Shortcuts Tab
