I have Lubuntu 14.04 installed on an ibook G4. Keyboard layout is set to "Macintosh". I cannot work out how to make accented characters. The usual method of using the option key (described here) does not work. For example option+e does not make an acute accent on the next vowel I key, but instead brings up the edit menu (both in leafpad and libreoffice). None of the other options for accents work either. Can anybody help with this?
Secondly, how do I bring up a terminal using only the keyboard? Ctrl+t does nothing.
