+3.  Status Window                               *lawrencium-status-window*
+
+The `hg status` window opened by Lawrencium has a few special commands 
+defined in it. Also, unless the global `lawrencium_define_mappings` is set to
+`0`, some commands are mapped to keyboard shortcuts, as detailed in the
+following descriptions.
+
+
+                                                *:Hgstatusedit*
+:Hgstatusedit           Open the file mentioned on the current line.
+                        Mapped to <cr>.
+
+                                                *:Hgstatusaddremove*
+:Hgstatusaddremove      Run `hg addremove` on the file mentioned on the
+                        current line, or on the lines currently selected in
+                        visual selection mode (see |visual-start|).
+                        Mapped to <C-A>.
+
+                                                *:Hgstatusdiff*
+:Hgstatusdiff           Open a diff window on the file mentioned on the
+                        current line, between the working directory version
+                        and the parent revision version. Similar to running
+                        |:Hgdiff| on that file.
+                        Mapped to <C-D>.
+
+                                                *:Hgstatusvdiff*
+:Hgstatusvdiff          Similar to |:Hgstatusdiff|, but use a vertical split.
+                        Similar to running |:Hgvdiff| on that file.
+                        Mapped to <C-V>.
+
+                                                *:Hgstatusrefresh*
+:Hgstatusrefresh        Refreshes the status window by running `hg status`
+                        again.
+                        Mapped to <C-R>.
+
+                                                *lawrencium-status-mappings*
+A few other mappings are available in the status window:
+
+   <C-N>                Jump to the next filename.
+   <C-P>                Jump to the previous filename.
+   q                    Quit the status window.
