Navigating in the Program Tree
If the Program Tree has the window focus, you can use the arrow keys for navigating between the elements.
If a single entry is selected, use the up and down arrow keys to select the previous or next entry.
To open or close a selected layer, use the right or left arrow key.
To expand the selection, use the up/down arrow keys while holding Shift.
If multiple entries are selected, use the up and down arrow keys to set the focus to the previous or next selected entry.
If the Program Tree does not have the window focus, you can use the keys W, A, D, and X to navigate in it: To select the previous or next element, press W or X, and to open or close the focused layer, press D or A, respectively.
If you are working with several separate windows that contain a Program Tree, the key commands are applied to the window that has the focus, provided that its lock icon is activated.
