+VIM text objects
+========================
+
+Integrates [opp][1] into Prezto, which implements [vim text objects][2] right into vim mode of prezto.

-In both cases the tmux server will be started and a background session

-By default every shell shares a set of windows but has an independent
-view. Detaching from one of these sessions removes the view but the
-open windows persist. This is accomplished by setting the
-`destroy-unattached` option to `on` for each session.
-
-Some users prefer that all new shells share the same session so that
-the view for each shell is in sync. This useful for advanced users
-that create multiple sessions and want to manually navigate between
-them. To accomplish this behavior set the `mode` option to `shared` in
-*zpreztorc*,
-
-    zstyle ':prezto:module:tmux:auto-start' mode shared
-
-You can customize the background session by creating a new session in
-your `.tmux.conf` file.
+With `auto-start` enabled, you may want to control how multiple sessions are
+managed. The `destroy-unattached` option of tmux controls if the unattached
+sessions must be kept alive, making sessions available for later use, configured
+in *tmux.conf*:
 
+    set-option -g destroy-unattached [on | off]
