Assuming you are referring to my pen table, it is attached. I am only working in gray and black with two line thicknesses however as can be seen form the image above, centerlines and axes appear in a reddish color which I don't mind so much and assuming this setting has been carried over from the default values, I will likely leave it alone. Below is a picture of the standard line conventions I am following. So far I not had the necessity to make any additional modifications to my pentable other than what I have for three first pens in order to maintain these line conventions.
Thanks for the info regarding mapkeys! I will consider it in the future when I have some spare time.

What other file types should I be concerned about?
