In LibreOffice Writer, Alt + E is the shortcut to activate the Edit menu, Alt + A for Table menu and so on.
I have a Dell Inspiron 3520. The layout I normally use is English (US). The one that I'm looking to use is Hindi (Bolnagri); which requires me to use the Alt key along with various letter keys regularly. It doesn't work, because Alt + many of these letters are shortcuts in LibreOffice Writer.
I want to disable these shortcuts. How do I achieve it? I am using Ubuntu 12.04 in case it matters.
