Hello, I would like to add custom tooltips to emacs. More specifically, whenever I hover on a symbol (function/variable) name with my mouse of I would like to see a tooltip with the symbol's definition. I know that I can find this kind of info with a tool like cscope but I have no idea how to attach the output of cscope to a tooltip. does anyone have a partial (how to link a callback to a tooltip in emacs in general) or a full (how do I actually link the output of cscope to a tooltip) solution to this?
Thanks, Nir
