Press F2 to open config file. Here all configurations is stored, such as the options you select in the righ-click menu.
Sometimes it can be useful to lock a setting so it will be the same att every start, yet you can change it during current session. Lock a setting by adding atribute lock=”true”.
Example: Blue background at every start but you can change it at current session (aslo see X11_color_names)
<add key=”background” value=”DodgerBlue” lock=”true” />
Example: Always open full screen
<add key=”rememberfullscreen” value=”True” lock=”true” />
<add key=”fullscreen” value=”True” lock=”true” />
