The Java Console indicates the active window component, called the focus, by either a blinking cursor or, in the case of buttons or check boxes, a blue border. On some screens, a default button might be identified by a black border. To change focus or activate a button, use the appropriate mechanism:
To move the focus from field to field within a window, use the Tab key. To move the focus backward through the fields, use Shift+Tab. If the focus is in an element such as a field that allows tabs to be used, then use Ctrl+Tab and Ctrl+Shift+Tab to move the focus through the fields.
Within a group of components, use the arrow keys to move up and down. For example, after you have tabbed to a particular list-item field, use the arrow keys to move among the list items.
To select a button on a window, change focus to the button, then use the spacebar to activate the button.
When a default button is identified on a window, press the Return key to activate that function.
To navigate through a hierarchical topology, use the up and down arrow keys to move between levels. Use the left arrow key to expand a level and the right arrow key to collapse a level.
