    The selection before inputting a key may have a range or not
    and it may be inside or outside of field or error attributes.
    A range may include the attribute partially, completely or together
    with surrounding text. It may also contain more than one attribute
    or no attribute at all.
    Depending on this starting conditions some actions are necessary:
    Attempts to delete a field are only allowed if the selection is the same
    as the field's selection. Otherwise the field has to be selected and the key
    input action has to be skipped.
    Input of text at the start of the field requires the field attribute to be
    corrected - it is not allowed to grow.

    In case of errors the appending of text should grow the error attribute because
    that is what the user usually wants to do.

    Backspace at the start of the attribute requires to find out if a field ends
    directly in front of the cursor position. In case of a field this attribute has to be
    selected otherwise the key input method is allowed.

    All changes outside of the error attributes switch the dialog mode to a "Undo edit" state that
    removes all visible attributes and switches off further attribute checks.
    Undo in this restarts the dialog with a current sentence newly presented.
    All changes to the sentence are undone including the ones before the "Undo edit state" has been reached

    We end up with 9 types of selection
    1 (LEFT_NO)     - no range, start of attribute - can also be 3 at the same time
    2 (INSIDE_NO)   - no range, inside of attribute
    3 (RIGHT_NO)    - no range, end of attribute - can also be 1 at the same time
    4 (FULL)        - range, same as attribute
    5 (INSIDE_YES)  - range, inside of the attribute
    6 (BRACE)- range, from outside of the attribute to the inside or
                including the complete attribute and something outside,
                maybe more than one attribute
    7 (OUTSIDE_NO)  - no range, not at an attribute
    8 (OUTSIDE_YES) - range, completely outside of all attributes

    What has to be done depending on the attribute type involved
    possible actions:   UE - Undo edit mode
                        CO - Continue, no additional action is required
                        FS - Field has to be completely selected
                        EX - The attribute has to be expanded to include the added text

    1 - backspace                   delete                      any other
        UE                          on field FS on error CO     on field FS on error CO

    2 - on field FS on error C
    3 - backspace                   delete                      any other
        on field FS on error CO     UE                          on field UE on error EX

    if 1 and 3 happen to apply both then backspace and other handling is 1 delete is 3

    4 - on field UE and on error CO
    5 - on field FS and on error CO
    6 - on field FS and on error UE
    7 - UE
    8 - UE
