Sub- and Superscript
With subscript and superscript, you can raise or lower text. This is especially useful for mathematical formulas or chemical compounds.
H_{2}0
f^{2}(x)H20
f2(x)
Subscript and superscript can also be disabled by placing a backslashe before the subscript or superscript:
H\_{2}0
f\^{2}(x)H_{2}0
f^{2}(x)
