When you open a document first in the grid tab, the document is collapsed so that it shows just the root element and its attributes. The grid disposition of the node names and values are very similar to a web form or a dialog. The same set of key shortcuts used to select dialog components are used in the grid. For instance moving to the next editable value in a table row is done using the (Tab) key. Moving to the previous cell employs the (Shift-Tab) key. Changing a value assumes pressing the (Enter) key or start typing directly the new value, and, when the editing is finished, pressing (Enter) again to commit the data into the document.
The arrow keys and the (Page Up/Down) keys can be used for navigation. By pressing (Shift) while using these keys you can create a selection zone. To add other nodes that are not close to this zone, you can use the mouse and the (Ctrl) key ( (Command) on Mac OS X).
The following key combination may be used to scroll the grid:
A left arrow sign displayed to the left of the node name indicates that this node has child nodes. You can click this sign to display the children. The expand/collapse actions can be also invoked by pressing the (NumPad Plus) and (NumPad Minus) keys.
A set of expand/collapse actions can be accessed from the submenu
of the contextual menu.The same actions can be accessed from the menu
