The PFD is designed around using the mouse and/or keyboard. There
are a number of instances in which either the mouse or the keyboard
can be used to perform the same function. One very important PFD
function for which the keyboard cannot be used is object inspection.
You can perform many of the tasks and manipulations on the icons in
the PFD by using object inspection. Place the mouse arrow over the icon
you want to inspect and press the right mouse button. An appropriate
menu is produced depending upon the icon selected (Stream,
Operation, Column, or Text Annotation).
