Thanks for your response Hans.

I don't want to argue with you Hans, as I know that you have better 
things to do. But for clarification: for a non-power TeX / CTX user this 
is information, that one usually doesn't get, as it makes deep interest 
in fonts creation necessary. On the other hand I don't expect you to be 
the one who teaches users about fonts, relationships or even the motives 
behind their creation. Thanks for your explanation though.

I see. Well I just used search on the CTX wiki to find information about 
selectfont, but neither selectfont nor \selectfont gives me any result. 
If it's something TeX related, then I have to say that I didn't start to 
use CTX to get into TeX before. Anyways this is where it starts. This 
time it's type-imp, other topics will make it necessary to search other 
source files and then it starts over... This is something for you, the 
other coders or users who want to tweak CTX or its components, but a 
standard user will never do this, as he usually doesn't know where to 
look for info.

In the sense that we (or let's even say just me) don't know where to 
look for information. I mean how many software do you have, where you go 
through its source files to understand how it does basic tasks? For me 
it's only CTX and as a consequence thereof Textadept, but for me that's 
already /too much/. So IMHO this must not be the future... Except for 
those who can't stop loving open source software that is usually made 
for a specific topic in the first place.

There you are right. There is so much documentation that it's 
overwhelming. For instance documentation on fonts goes over several wiki 
pages. Suffice it to say you have to know what you are looking for, and 
not where. And the more you start searching, the more wiki pages you 
have to go through. A better approach might be to merge several pages 
that belong to a single chapter to one single wiki page. But that's just 
my opinion. Another example: I have found different links to manuals 
like Hoekwater's or Hagen's (on the wiki). But on several pages you get 
links to several versions of the manual, for instance I found one link 
to Hoekwater's 2003 version and to 2011 or 2013 version (I don't 
remember the exact dates as I deleted them both). Some time later I read 
that there is an online manual somewhere in the download area, that has 
to be built first. But there seems to be no manual for Windows users how 
to do this. I.e. one has to get some basic Linux info or similar, just 
to build a manual. I don't find this to be user friendly at all. That 
being said, the US army has a code name for something like that: Charlie 
Foxtrot (abbreviation for cluster fuck, i.e. chaos). So indeed there is 
plenty of information, but most of it is written from the POV of a long 
time user or a programmer. There clearly lacks documentation from the 
POV of a simple user who has never used TeX or its kind.

I mean sure, it could be only me who has a hard time understanding CTX, 
but since I have found out many things about CTX without asking anybody 
but reading information that is already there, the fact that I found out 
how to change only the math font after approx two years somehow shows 
me, that it's not only some lack of my will to read all the pages 
several times to understand CTX but also the lack of passion in the 
documentation.

Still I won't give up. So far I am a happy CTX user.

Cheers, Sebastian
