title: How do I write subscript lowercase letters in a string
body: <p>As the question says, how do I write subscript letters for example, Fnet (net is subscripted), in a string?</p>
  
  <p>Is there any shortcut key for creating a subscript lowercase letter? I just found few subscript lowercase letters, ₐ ₑ ᵢ ⱼ ₒ ᵣ ᵤ ᵥ ₓ, other letters are missing.</p>
