@ -1923,6 +1923,11 @@ When displaying text which can contain formspec code, e.g. text set by a player,
use `minetest.formspec_escape`.
For coloured text you can use `minetest.colorize`.
Since formspec version 3, elements drawn in the order they are defined. All
background elements are drawn before all other elements.
`list` elements are an exception here. They are drawn last. This, however, might
be changed at any time.
**WARNING**: do _not_ use a element name starting with `key_`; those names are
reserved to pass key press events to formspec!
