Although Kate already offers a good completion mode, Kile extended code completion to support some special methods especially for L^AT_EX. Five different modes are integrated. Three of them work on demand, the other two are autocompletion modes. All modes can be configured to work very differently at Settings → Configure Kile....

Automatic Environment Completion

When you begin a new environment, typing \begin{environment}, Kile will automatically add an \end{environment} command, with a line in between for your text.

Autocompletion can be turned off in the L^AT_EX section of Settings → Configure Kile... → LaTeX+Environments.
