@dror-sign: I have tested with Ctrl+O (File→Open...).
Indeed, when they keyboard layout is in Hebrew, Ctrl+O in Libreoffice does not work.
However, Ctrl+O in LibreOffice for at least Greek and Russian works.
Therefore, this inability for Ctrl+... shortcuts not working in LibreOffice for Hebrew is an issue by itself, that is specific to Hebrew (and needs a new report that is specific to Hebrew and other layouts that are affected in the same way).
