Classification: / Key,
Info: On a printing calculator like the TOSHIBA: BC1271P, the key marked with an I combined with a Rhombus-symbol stands for Item Subtotal.
It combines the functionality of the Item Counter (I) and the standard Subtotal symbol (Rhombus is the universal accounting symbol for a subtotal).
It performs the following functions during an active calculation:
Print Current Item Count:
It prints the exact number of entries (items) you have typed into the calculator up to that exact moment.
Display Current Subtotal:
It prints the running tally/subtotal of your additions or subtractions without clearing the machine's memory.
Keep the List Active:
Unlike a final Total key [*], pressing the [I(Rhombus)]-key allows you to safely view your progress and continue adding more items to the same list afterward.
