"Text in Right Hand Top Window" I believe you are talking about the Console which appears when a route
is active, and it shows route data.
Options > User Interface > Font Settings.
Options Setting | Official OpenCPN Homepage
Console font settings for black data box that appears when a route is active.
Also see activate route
Marks and Routes | Official OpenCPN Homepage
More about Console black box with information in it?
Are you talking about the yellow box that displays information about routes, legs etc?
The size of that text is also controlled from Options > User Interface Fonts.
PS: Note regarding User Manual
The word Console Menu should appear at the top, I think.
Also we should be more explicit in referring to the "Console" where we refer to it.
I notice that
Auto Follow Auto Follow | Official OpenCPN Homepage
Routes and Mark Manager Route & Mark Manager | Official OpenCPN Homepage
do not show or discuss the Console window
and should probably have a link back to here http://opencpn.org/ocpn/sites/defaul...ifun/font1.png
We need a dedicated "Console" Page with description which should be located right after "Chart Info" Chart Info | Official OpenCPN Homepage
Then the other pages can refer to it as is appropriate.
