+=== Moving containers/workspaces to marks
+
+To move a container to another container with a specific mark (see <<vim_like_marks>>),
+you can use the following command.
+
+The window will be moved right after the marked container in the tree, i.e., it ends up
+in the same position as if you had opened a new window when the marked container was
+focused. If the mark is on a split container, the window will appear as a new child
+after the currently focused child within that container.
+
+*Syntax*:
+------------------------------------
+move window|container to mark <mark>
+------------------------------------
+
+*Example*:
+--------------------------------------------------------
+for_window [instance="tabme"] move window to mark target
+--------------------------------------------------------
