%chars displays all of them, on less than a screen (50 characters per 
line x 20 lines make 1000 characters ;-). It is illustrated in the 
provided help page.
And it is hierarchical. So remembering 2 to 10 trivial fields names is 
enough (instead of 1000 codes), if you wish to display subsets.

I may not understand the question. Please see the documentation. Both 
are already included in my current %chars illustrated in the doc.

+1. That's the point. This is why most often i display the whole %chars. 
Just %chars. Without any codes.
