Hello again, I have finally worked out the keyword editing problem. I think it is not well written, I am still struggeling with many things that are as they are and basically still learning to read and adjust code. It is very hard for me to try to do that as I'm used to C#, C++, Java etc. Reading Smalltalk code in Pharo just seems to be so much more complex to me .. Anyway .. now it works only for UntypedModel, which is a problem still, that I have no idea how to fix at the moment. There should be two models with this I believe, but the NECModel class isn't written in the way that it could have multiple models (one for the receiver of the whole keyword and one for the receiver of the parameter of the previous part of the keyword .. .). If anyone would like to have a look and say what you think, what I'm doing wrong, what am I not seeing, please reply.
