Hello. It doesn't seem to be keyboard issue, since I tried different combos, i.e. wallwalk - shift, jump - any other key (which works in other situations, has to) or even wallwalk - shift, jump - mouse button (doesnt work for jump, works pefrectly for any other situation of course). It doesn't seem to be my hardware limitation, so I am really amazed how wallwalk + jump works for some of You... Maybe it's linux issue ? Anyway I am using toggle wallwalk now and starting to get used to it. Thanks very much for all of Your answers.
