To change mode, you must open the Action Menu and then change it. To open the menu, first you should confirm the setting for "Center button" is [Action menu] and "4-way selection" is [On].
What's what I did since the beginning. 4-way selection is "ON" and Center button is "Action Menu"
Next step, after pressing and holding the key you set in "4-way selection", press the Center Key, the Action Menu should be shown.
OK the focus is already in "Action Menu" item inside the combobox. But when I press the center-key it just expand the combobox viewing the "None" item as well! when I press center key again it just shrinks back. No menu is shown.
My Samsung i780 has optical d-pad but it just functions as normal d-pad so it should be compatible with MagiKB. I also installed AEButtons but it never touches the d-pad area. I also installed chgFingerMouse to quickly toggle between mouse mode and d-pad mode. But i'm always in d-pad mode while configuring MagiKB. Maybe i'll just experiment in disabling some. I'll just get back after the results.. thanks
