+    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
