Answer 1

In WinEdt:

1. Type } after \begin{document}, that is: type

   \begin{document}}
   

   You can also use > after \begin{something} to change the environment name to something else. For example, typing > after begin{tabbing} in the following example

   \begin{tabbing}
   ....
   \end{tabbing}
   

   prompts you for inserting a new environment name. If you insert tabular you get

   \begin{tabular}
   ....
   \end{tabular}
   

   Moreover, the string \end{{ triggers environment completion. It searches for the last opened environment and closes it.
