Vim LaTeX \begin autocomplete -

i writing mathematical paper using latex , pretty content vim, however, thing miss texmaker automatically generated \begin{}\end{} blocks. wondering how might implement such functionality using inoremap command in same way texmaker, after you, example, type \begin extends \begin{<env>} \end{<env>} , places cursor between braces , after replace <env> environment replaces both in \begin{} , in end{} command.

is possible vim script?

this command take word under cursor , make block wanted

     :noremap \b cw\begin{<c-r>"}<cr>\end{<c-r>"} 

keep cursor @ start of word , press \b in normal mode desired output.
