Hello, I'm not sure who I need to ask, but I wish to add a C++ feature to XEmacs that would give you a pop-up list box after pressing the '.' key. Something similar to VC6++. For instance if you have a vector<Type> v; later in the code you type v. after the dot a pop-up list box would be displayed showing all the options you may used. e.g push_back , or any other method you may have created. Is anyone currently working on a similar project. I know have a limited knowledge of Lisp at this time, and it would be helpful it you could point me in the right direction of which files I might need to look at to make this feature. Cliff Dunford
