With this resource, you can just look for the symbol of interest, and then click it. That will take you to the apropriate section. In that section there will be links to photographs and text discussions. In lieu of mouse clicks, using the keyboard, type the letter beside the highlighted box to go there.
In this example, the cursor (pointing finger) is shown over the Section F symbols, which is indicated to the reader by the red box and title line. As you move the cursor, the activated section of the screen changes with it.
This sample is just a small section of this important part of the program. Essentially all chart symbols are represented in this Index in one form or another.
