The default line settings can be modified by the Theme setting so it must be able to be done. If you only want to change the line colour then you could modify the colour palette but if you want to change the line thickness you will need to fiddle with the theme (which hasn't been a happy hunting ground for me).

Perhaps it can be done in a theme, but I have no idea how. Using a Building Block/AutoText entry is a lot easier.

Thank you, Stefan Blom and Guessed.
I have finally got round to trying your suggestions. The Building Blocks solution is nice and easy.

As for the Themes possibility, I would have to get acquainted with making changes there. Have never done that.

Thanks again and... one more question:
Is it possible to use a Building Block with a keyaboard shortcut, or an icon?

Cheers Tomasz
PS I know I can use Left Alt + V + B and select a BB.
