When launched, focus is on the Dimensions tree that you will customize to later generate dimensional measures. Use the keys described in “Using Trees” to work with the dimensions. Press the Properties key (to the left of the Alt button on most keyboards) to activate the context menu that enables you to create a dimensional hierarchy as follows:
Move Up: Moves the selected dimension member up
Move Down: Moves the selected dimension member down
Ctrl Up: Moves the selected dimension member up to be the child of another dimension
Ctrl Down: Moves the selected dimension member down to the child of another dimension
Press Ctrl+Tab to move focus from the dimensions tree to the details pane that provides information about selected dimensions. Press Ctrl +Tab again to move from the description field to the Save button.
