How to display variables in Taglist window in vim

There is a variable s:tlist_def_cpp_settings in Taglist plugin (.vim/plugin/taglist.vim) that defines which elements are shown by default.

I extended it to:

let s:tlist_def_cpp_settings = 'c++;n:namespace;v:variable;d:macro;t:typedef;' . \ 'c:class;g:enum;s:struct;u:union;f:function;m:member;' . \ 'p:prototype'

According to taglist manual you can also define tlist_cpp_settings in your .vimrc with similar value.

For other languages different variables exist.
