+TAB LOCAL DIRECTORY
+
+When you open a new tab page, it uses the directory of the window in the
+previous tab page from which the new tab page was opened. You can change the
+directory of the current tab page using the `:tcd` command. All the windows in
+a tab page share this directory except for windows with a window-local
+directory. Any new windows opened in this tab page will use this directory as
+the current working directory. Using a `:cd` command in a tab page will not
+change the working directory of tab pages which have a tab local directory.
+When the global working directory is changed using the ":cd" command in a tab
+page, it will also change the current tab page working directory.
