Thanks for the wonderful tool, it has been my favorite in ubuntu for cpp developing.
Changing to v5.0.6213 is great, but there is a very minor problem for me to set up the "show abbreviation" shortcut, I tried to set it to "Ctrl+/", but it does not work. I am using ubuntu precise 12.04, it used to work well in V4.1. If you have time please take a look it, of course it is not a big deal, might just be my system problem, I am not sure though.
Thanks again for the effort!!!
