Change the background colour of a piece of text?

[Christian Ridderström]

Hi,

I can change the foreground colour of a piece of text using the dialog 
opened through the menu:
        Edit->Test Style->Customized ...

However, how can I do the same for the background colour?

Note: It's not critical, and my use case really ought to use a character 
style, but I got curious.

regards
