Help with viewlist and box for text

I want that if the text in the box has a specific letter, it must appair in a specific part of the screen. Example : i write the formule F = ag, so there is F in the box and the formule must appair in the viewlist for the formule with F. I don't know how to do that so thanks if someone will help me

Can you be more specific?

Is this

  • a dictionary lookup problem?
  • a hidden Arrangement lookup by letter (F)?
  • how to use parallel ListViews?
  • something else?

Maybe you want something like this?
