A workaround to get shortcuts in non-Latin scripts to work again is to kill any IBus processes.
I killed
/usr/bin/ibus-daemon --replace --xim --panel disable /usr/lib/ibus/ibus-dconf /usr/lib/ibus/ibus-x11 --kill-daemon /usr/lib/ibus/ibus-engine-simple
and then I could "Select All", or start "Alt+F" to get the File menu.
Thus, IBus is interfering with GTK+ apps, even if for those apps the default GTK+ IM is active.
