[TYPO3] Changing text properties in the RTE edito

[Marcus Wendel]

Hello all,

How can I change the way text is displayed in the RTE editor without 
changing how the result looks to the visitors?
For example there is to much space between the lines in the editor (much 
more than in any browser viewing the finished results) and that is 
wasting a lot of screen space, so how can I change it?

Thanks.
