Dear All,<br><br>In attachment there is a picture. my question is which settings should I  modify  if I want to change the background color. <br><br>I know in &quot;edit/preference/terminal&quot; , I can change the terminal window&#39;s background color( domain 2).  but how to change the main writing window ( domain 1), the &#39;white color&#39; looks uncomfortable.<br>

<br>Thank you for reading my boring question.<br clear="all"><br>-- <br><br>Shenghui                 Student<br>Major:                    Physics<br>HuNan University         China<br>
