As each frame is drawn in a layout window, it assumes a
hierarchical position. Each new frame automatically becomes the top
level
. You will learn to treasure this function if you work
often with layouts that contain frames on more than two superimposed
levels. If you wanted to move a frame down a level with such layouts
previously, then this required extensive move actions. With the
function Shift one level down
you can accomplish this task much
more easily. Naturally you can also move several frames at the same
time.
