General Principles for Interaction

The dialogs are presented as list boxes with picking possibilities and a key-in field for selection. The key-in field will always be initially current when the dialog is first shown, which allows for alphanumeric input in all cases. Depending on what has been keyed in, the list box alternatives are searched in alphabetic order. If default designations are defined (as explained below), then also these ones will be selectable in the same alphabetic order.

The hole selection can be used as example. If character H is keyed in, the menu item representing a HE hole will be the selected one. Furthermore, the first default designation will be used, which maybe will result in a hole selection represented by the designation HE200*100. If, on the other hand, HE25 is keyed in, then the designation HE250*125 will be selected.
