changeable keymap is scheduled for version 0.3.8, see our roadmap, and to the other question .. well currently we have support for 27 languages, and will become much more. but thats only highlight you mean in future with outocompletition and the other stuff that will come soon. well, i would like to support as much languages as possible, but i do first to help myself out. but everything will be written configable so that python fans can easyly create an python mode my witing an text files with some keywords sttings and rules they wish. thats the way it was planned from the start but for myself need only perl, HTML, CSS, and conf maybe YAML later. Its a long road to go.
