See, I think that is where you and I are going to divide a bit. I don't think the dictionary has comments anymore (I believe introduced circa 3.x? 2.x?) which were incredibly helpful. As for pdf docs, there are programs I could use I'm sure that would allow me to search it. Firefox, for instance, if I hit Open file and browsed to the location (where ever they put it, I lost track of it some versions ago), however it doesn't open in Firefox by default on linux, that is something I would have to really want to do (i.e. go find out where it is).
the beauty of the current documentation is that it includes all the stuff in earlier versions and clearly states if an item was introduced later (i.e. version 2, 4, 7, 8 or 9)
That has been the format since 2.x. for the dictionary, but "documentation" is a pretty broad descriptor. Again, due to my own ignorance about the current state of the documentation from my lack of experience with same, I haven't any relevant thing to compare it to.
I don't think it is either as fast or easy to find what you are looking for in the current model as the much MUCH older model, but that is an opinion, not a fact. From what I saw of the guide back when I was playing in 8.x, I think it was a vast improvement over the .pdf.
I did find a number of things in the help folders I never knew existed before, but I count that as another knock on the way things went in the help section.
But that is really a discussion for another place and time, now that we've run rampant all over Craig's post, heh, i'll make my apologies and exit.
*Edit - Just to give you an idea of what the dictionary currently looks like when you click on it in a (non supported) linux distro, this should give you some idea. Nothing is resizable either.
When I go to look something up when I do use Lc9, I actually use Brian's dictionary, or Max's wiki, or Bernd's excellent tinyDictionary.
