I have done several steps to use Hebrew as secondary language and I ran into
several issues:

1) After defining Hebrew as secondary language, desktop titles, menus and text
documents (by kwrite, internet browsers, etc.) are displayed in Hebrew (or
multilingual), but I cannot swap keyboard to write in Hebrew.

2) I have tried to remove secondary language through Yast-Software-Language
(gui)
but no change done and desktop titles and menus are still displayed in Hebrew.

3) I would prefer having desktop titles and menus in English - the primary
language.

4) I miss easy way to swap keyboard from primary language to the secondary and
vice versa in same application (like kwrite) even in same row/line.
