 		The above code will create a [SpinBox], disable context menu on it and set the text alignment to right.
 		See [Range] class for more options over the [SpinBox].
 		[b]Note:[/b] With the [SpinBox]'s context menu disabled, you can right-click the bottom half of the spinbox to set the value to its minimum, while right-clicking the top half sets the value to its maximum.
-		[b]Note:[/b] [SpinBox] relies on an underlying [LineEdit] node. To theme a [SpinBox]'s background, add theme items for [LineEdit] and customize them.
+		[b]Note:[/b] [SpinBox] relies on an underlying [LineEdit] node. To theme a [SpinBox]'s background, add theme items for [LineEdit] and customize them. The [LineEdit] has the [code]SpinBoxInnerLineEdit[/code] theme variation, so that you can give it a distinct appearance from regular [LineEdit]s.
 		[b]Note:[/b] If you want to implement drag and drop for the underlying [LineEdit], you can use [method Control.set_drag_forwarding] on the node returned by [method get_line_edit].
