I normally work with a dark background and light gray text when using Emacs for general text work or code. If you want to open a document created in OpenOffice Writer, and you want to get the same look while you edit the document. You can do that.
To get the OpenOffice Writer look, first change the colors
Next we set the text color to dark
We have the colors, now we need to change font type and font size.
Press Ctrl key and right click mouse in Emacs frame. Emacs displays a menu. Select Options > Default Font. Emacs will pop up a font selection dialogue box.
Click okay to finish.
