Keyboard navigation in the Configure dialog is wrong/unexpected:

• Enter: Pressing enter in search field closes the dialog
  1. Open Configure Dialog
     • Search field is focused
  2. Type something into the search field and press enter
     • Configure dialog is closed as the "OK" button was selected
     • Expected: focus on first field in the main panel

• Tab: You need to tab through all buttons to reach the icon menu and then the main panel. Also the last field in the main panel should tab to the OK button and not to the search field.
  1. Open Configure Dialog
     • Search field is focused
  2. Press tab
     • Button "Defaults" is focused
     • Expected: Selected Menu item of the vertical icon menu (to be able to change the menu item fastly)
  3. Press shift+tab twice
     • Last field in main panel is focused
     • Expected: OK button
