+Tab
+===
+
+Description
+-----------
+
+Add a bar at top or bottom of the screen with a label for each <i>displayed</i>
+window. This feature was primarily designed for the monocle window layout. In
+this mode the labels appear like tabs, transforming the layout into a
+<i>tabbed</i> layout. Navigating from window to window can be done by clicking
+on the window tabs or using the usual Mod1-j, Mod1-k keys. The bar can be
+enabled and disabled at runtime. This patch can be used as an alternative to the
+[tabbed](http://tools.suckless.org/tabbed/) tool. It differs in two ways: the
+''tab'' feature is limited to the monocle mode; it works with any application
+without requiring to support the XEmbed protocol nor to define in advance the
+set of applications to be supported.
+
+Usage
+-----
+
+With the default configuration, use the key combination Mod1-w to toggle the tab
+bar display. Switch focus to a window with a mouse left-click on its tab or by
+using the usual Mod1-j, Mod1-k commands. Usage is also documented in the dwm man
+page once the patch is applied.
+
+In the right corner of the tab bar the window ''tag'' currenlty selected for
+display is recalled. This feature is interesting when the standard status bar is
+disabled. If multiple tags are selected for viewing then three dots are
+displayed without more details.
+
+Configuration and installation
+------------------------------
+
+Apply to the dwm code the patch you can find in the download section below. If
+you don't already have a dwm config.h file, the make command will produce one
+that contains already the necessary configuration lines. If you already have
+one, then you must add to it the following lines:
+
+ static const Bool showtab = True; /* False means no tab bar */
+ static const Bool toptab = False; /* False means bottom tab bar */
+
+The first variable tells if the tab bar must be displayed by default; the second
+one if it should be displayed on top of the screen or at bottom.
+
+If the tab bar is displayed at bottom, then a better experience will be obtained
+with the variable resizehints of the config.h file set to False. This setting
+prevents possible gap between the windows and the tab bar. You can find more
+details about this variable and gaps between windows in the dwm FAQ.
+
+In order to allow enabling and disabling the tab bar by pressing Mod1-w, add to
+the `keys` array, the following element:
+
+ { MODKEY, XK_w, toggletab, {0} }
+
+Selection of a window by a mouse left-click on its tab is enabled by adding the
+following element to the `buttons` array:
+
+ { ClkTabBar, 0, Button1, focuswin, {0} },
+
+An example on how to insert these line can be found in the default config file template, config.def.h.
