I have been using MacVim for a while. It has always been the non-terminal version. Recently I started using tmux and I would like to be able to use vim inside a tmux session. Only when I started to tweak my settings, I realised that the terminal experience will not be as smooth as the standalone MacVim one.
I am not talking about speed issues etc, it is mostly things like key mappings behaving differently etc. I already gave up trying to get the Option (Alt) key working, but at least I would like to have things stable in general.
For example a key mapping such as that works perfectly in the non-terminal vim suddenly becomes , CTRL is no more a modifier? Discrepancies like that just make things extremely hard.
What are the most important configuration options that might improve MacVim's stability when running in the terminal?
