I have knowledge about 'Kile' more or less. Now I am using 'Texmaker'. But there is a problem in it. In Kile when we write \begin{env} it automatically write \end{env} from the following :
Settings => Configure Kile => LaTeX => Environments => making tick mark on "Automatically complete \begin{env} with \end{env}" we can set it.
But in 'Texmaker' automatic environment is not working. How can I do so.
