*
* 1. Field at specified offset is not an Input field
* "Field at specified Offset is not an input field"
*
* 2. If in finding the specified offset, the end of the
* screen is reached.
* "Specified Offset is outside of screen"
*
* 3. If during a screen wrap (cursor movement causes a screen wrap),
* and no input field can be found.
* "Error finding Input Field after Screen Wrap"
*
* This function will wait for a keystroke, and abort the program. If
* this action is not desired, then you may provide your own function
* in its place. Your routine may perform a normal return, and
* edit_input_fields will return 0.
