| Button | Either Enter or Space will activate the button, causing the same action as a left click. |
| ComboBox | Up or down arrow keys display the popup menu and allow selection of ComboBox values. Space or Enter selects a ComboBox item from the popup. If editable, alphanumeric keys cause an edit.
|
| Dialog | If the dialog has an accept button defined, Enter key activates it. The dialog is modal and blocks all other keyboard events.
|
| Content Area (IFrame) | Press Ctrl+F6 to enter a frame, then you may need to press Tab to select the first focusable item. Press Ctrl+Shift+F6 to exit the content area of a frame and return focus to the frame itself.
|
| List | The up or down arrow keys move selection focus up or down through the list elements. The selection is continually updated. An arrow key press results in a selection event. Ctrl+Up or Down key: item focus moves up or down without changing the current selection. Spacebar can be used to add the focused item to the selection. Shift+Up or Down key: item focus moves up or down and the newly focused item is added to the selection. Note: If the list supports only a single selection, the Ctrl and Shift modifiers have no effect.
|
| Tab Bar | Left or right arrow key moves selection focus and selects the new tab immediately. Selection focus wraps around the ends of the tab bar. |
| Text Field | If editable, alphanumeric keys cause an edit. Tab proceeds in the tab order. Tab cannot be entered as a character in the text field.
|
| Tree | The left and right arrow keys collapse or expand the current node if it has children. If it has no children, there is no effect. The expansion is non-recursive. However, if the tree is capable of remembering previous expansion state of any subnodes, it should do so. |
