I guess you Coeluh are after something like they have at the AHK forums where they have the option to expand the code input window to show the full text of a multilined code.
I actually thought they did have an option at one stage to copy that code to the clipboard at AHK but it may have been on another sites forum.
I don't think it would be impossible just to have an input window that has code to include the options to (a) expand-collapse (b)copy to clipboard
The initial posting would only show one or two lines of code to save message space.
The benefit would be when there are updates amendments to the code with repetitive showing the original then the amended it will not obtrusive to the non interested.
