+menu\_clients\_current\_tags
+----------------------------
+
+Similar to `awful.menu.clients()`, but this menu only shows the clients
+of currently visible tags. Use it with a key binding like this:
+
+    awful.key({ "Mod1" }, "Tab", function()
+        awful.menu.menu_keys.down = { "Down", "Alt_L", "Tab", "j" }
+        awful.menu.menu_keys.up = { "Up", "k" }
+        lain.util.menu_clients_current_tags({ width = 350 }, { keygrabber = true })
+    end),
+
+magnify\_client
+---------------
+
+Set a client to floating and resize it in the same way the "magnifier"
+layout does it. Place it on the "current" screen (derived from the mouse
+position). This allows you to magnify any client you wish, regardless of
+the currently used layout. Use it with a client keybinding like this:
+
+	clientkeys = awful.util.table.join(
+		...
+		awful.key({ modkey, "Control" }, "m", lain.util.magnify_client),
+		...
+	)
+
+If you want to "de-magnify" it, just reset the clients floating state to
+`false` (hit `Mod4`+`CTRL`+`Space`, for example).
+
+niceborder\_{focus, unfocus}
+----------------------------
+
+By default, your `rc.lua` contains something like this:
+
+	client.connect_signal("focus", function(c) c.border_color = beautiful.border_focus end)
+	client.connect_signal("unfocus", function(c) c.border_color = beautiful.border_normal end)
+
+You can change it to this:
+
+	client.connect_signal("focus", lain.util.niceborder_focus(c))
+	client.connect_signal("unfocus", lain.util.niceborder_unfocus(c))
+
+Now, when a client is focused or unfocused, Awesome will look up its
+nice value in `/proc/<pid>/stat`. If it's less than 0, the client is
+classified as "high priority"; if it's greater than 0, the client is
+classified as "low priority". If it's equal to 0, nothing special
+happens.
+
+This requires to define additional colors in your `theme.lua`. For example:
+
+	theme.border_focus_highprio  = "#FF0000"
+	theme.border_normal_highprio = "#A03333"
+
+	theme.border_focus_lowprio   = "#3333FF"
+	theme.border_normal_lowprio  = "#333366"
+
+tag\_view\_nonempty
+-------------------
+
+This function lets you jump to the next/previous non-empty tag.
+It takes two arguments:
+
+* `direction`: `1` for next non-empty tag, `-1` for previous.
+* `sc`: Screen which the taglist is in. Default is `mouse.screen` or `1`. This
+  argument is optional.
+
+You can use it with key bindings like these:
+
+    -- Non-empty tag browsing
+    awful.key({ altkey }, "Left", function () lain.util.tag_view_nonempty(-1) end),
+    awful.key({ altkey }, "Right", function () lain.util.tag_view_nonempty(1) end),
+
+where `altkey = "Mod1"`.
+
+prompt\_rename\_tag
+-------------------
+
+This function enables you to dynamically rename the current tag you have focused.
+
+You can use it with a key binding like this:
+
+    awful.key({ modkey, "Shift" }, "r", function () lain.util.prompt_rename_tag(mypromptbox) end)
