Since two days, I am the proud owner of a Lubuntu operating system. When I press the space key on my desktop, I want it to pause the audio that I am playing. Instead, it lowers the page that I am currently in. How can I change this? Also, I would like to change the keyboard settings in order to be able to make a “é” by first pressing ‘ and then e. When I do that now it just becomes ‘e instead of é.
