This appendix presents common keyboard shortcuts and mnemonics in alphabetical order and summarizes JFC-supplied keyboard navigation, activation, and selection operations in a series of tables (arranged alphabetically by component). The left column describes a keyboard operation (for example, left arrow key) and the right column of each table describes the corresponding action (for example, moving focus to the left).
Navigating means to move the input focus from one user interface component to another; activating refers to operating the component; selecting means to choose one or more user objects such as text or icons, typically for a subsequent action. For an overview of these concepts, see Keyboard Navigation and Activation.
In general, navigating between components uses these keys:
Some actions in the table list several possible keyboard operations, separated by a comma. For example, both Home and Ctrl-Home move focus to the beginning of a list.
Ensure that you provide multiple operations that take
into account the
differences between operating environments if your application runs on
several.
Some of the keyboard operations described in the
following tables might be
temporarily incomplete or not implemented. However, these key sequences
should be reserved for future versions of the JFC and the Java 2 platform.
The arrow keys are insensitive to the component
orientation feature in the
Java 2 SDK. (Component orientation is the automatic positioning of
components to reflect the writing system of a locale--for instance, left to
right, or right to left.) For example, the right arrow moves the action right
regardless of the orientation of the locale.
The following table provides an alphabetically sorted list
of common keyboard shortcuts. Use this table to see which keyboard shortcuts are used and which are available. (You can use these
shortcuts for other purposes if your application does not provide the associated function and will not add that function in the
foreseeable future.) For a table of keyboard shortcuts organized according to menus, see Table 8.
