how to make keyboard shortcuts work while in another language [duplicate]

Solution 1:

I'm afraid that's a known bug in libreoffice specifically and Unity in general. I suggest you read through those pages but a user has found a possible workaround:

Hello everyone!

After months of switching layouts and banging my head against this bug, I thought I should check LibreOffice settings (I'm using 4.1.5.3 now). What figures? I did find something. And in just a few clicks.

This is not a bug! It's simply a matter of configuration.

For the regular keyboard shortcuts (like Ctrl+C, Ctrl+V, etc.) to remain operational in LibreOffice applications while using a non-latin keyboard layout (like Greek or Russian), go to Tools -> Options -> Language Settings -> Languages, check the Ignore system input language option, save, and Bob's your uncle.

Hope this helps.

Cheers!

PS Technically, though, shortcuts still remain language-dependent. This means if you enable this option, you will have to set your document languages manually.

That might fix your libreoffice issue but you will still have the same problem in other programs.
