Answer:
Superscript or Subscript
Explanation:
The superscript or the subscript is a type of character which is set a little lower or more than the normal line of type. And it is generally small as compared to the other texts. The subscript does appear at or less than the baseline, and the superscript is above. And for the superscript, you need to press the Ctrl + Shift + + ( press and at the same time also hold the Ctrl and the Shift, and finally press the +). And for the subscript, you need to press the Ctrl + Shift ++(Press and at the same time also hold the Ctrl. and finally press the =). And pressing the corresponding shortcut once again, you will be back to the normal text.
