This question is not the same as In vim, how can I quickly switch between tabs?, but what I want is a bit similar to it, since we are all trying to find shortcuts when editing with vim:)
Now I am in the following mode:
set number syntax on colorscheme desert
Can I switch to the other mode quickly without typing 3 command?
That would be more convenient than inputing lots of commands.
set nonumber syntax off colorscheme blue
