+7. Touch Bar						*macvim-touchbar*
+
+Touch Bar in MacVim works similar to the toolbar (see |macvim-toolbar|).  The
+difference is that you use the special menu "TouchBar" instead of "ToolBar": >
+	:an TouchBar.Hello          :echo "Hello"<CR>
+
+The separators work similar to how toolbars work: >
+	:an TouchBar.-Sep-          <Nop>
+	:an TouchBar.-space1-       <Nop>
+	:an TouchBar.-flexspace2-   <Nop>
+
+The first example is a Vim separator (see |menu-separator|) and injects a
+space between two buttons. The second creates a smaller space than a normal
+separator and are specified by names that begin with "-space" and ends with
+"-". The third creates a flexible empty space which will shrink or expand so
+that items after it will be right-aligned, and is specified by names that
+begin with "-flexspace" and ends with "-".
+
+You can specify icons for Touch Bar buttons the same way for toolbar icons.
+Touch Bar icons should ideally be 36x36 pixels, and no larger than 44x44
+pixels. You can also use default template icons provided by Apple by using
+their template names. An example: >
+	:an icon=NSTouchBarListViewTemplate TouchBar.ShowList <Nop>
+
+This feature only works on Mac devices that come with Touch Bars. On the ones
+that don't, nothing will show up.
