Index/Reverse Index The R INDEX and INDEX keys are used to place your typewriter in the superscript and subscript modes. In the direct type mode, the platen will rotate slightly up or down to allow typing of super and subscript characters 1/12" higher or lower than the base line (see micro indexing below). In the display mode, the platen will not move, but an up or down arrow symbol will appear to indicate the super or subscript modes. To put your typewriter in the superscript mode, press the R INDEX key, and to put it in the subscript mode, press the INDEX key. Type the character that you wish in super or subscript. With the Reverse Index key or Index key, you can type 23 or H20. Now press the opposite key to release your typewriter from the super or subscript modes. Note: If your typewriter is in the automatic underline mode, superscript and subscript characters will be typed with an underline. Micro index and micro reverse index This function allows you to set more delicate settings in superscript and subscript. Pressing the CODE + R INDEX or CODE + INDEX keys will place your typewriter in the super or subscript mode, as with the R INDEX and INDEX keys, but the characters typed in this mode will only be 1/48" above or below the base line. Note: The micro index and micro reverse index mode will clear the line correction memory. CEA
