Transcribed Image Text:Modify the temperature conversion program so that it responds to the
user's press of the return or enter key. If the user presses this key when the
insertion point is in a given field, the action which uses that field for input is
triggered.
Be sure to use the field names provided in the comments in your starter
code.
