The described bug implies seriously limitation on what can be done with keyboard in this dialogue window.
Steps to Reproduce:
1) Launch Calc.
2) Hit Ctrl-K.
3) Hit Tab.
4) Hit Alt-X.
The button «Help» gets focus (after the 3rd step).
Nothing happens (after the 4th step).
The next field «Frame» gets focus (after the 3rd step).
The field «Text» gets focus (after the 4th step).
User Profile Reset: No
As soon as any of the buttons of the bottom button row gets focus, there is no way to take focus to any GUI element but the buttons no matter how many times Tab is hit (user is forced to use mouse). The Alt-Underlined keys shortcuts do not work either (Alt-X is just an example).
