as mentioned kind = "outline" will be in the next upload so with the 
current one you need to use the also posted here for ... endfor variant



also when i edit the code and replace metapost part like this:

\startMPcode
      draw lmt_outline [
          kind = "outline",
          text = "\getbuffer[MyText]",
       ]
          withcolor red
       ;
\stopMPcode

it produces a selectable hidden text on top of body and red text that 
drawn by metapost below of that.


How can this problem be solved?

i attached the codes and pdf results.

we're talking outlines so that is paths which implies no search but you
can do this (Keith and/or Hraban will explain and/or wikify it)

\starttext

\startbuffer[MyText]
      \definedfont[name:texgyrepagellabold*default]foo f o o%
\stopbuffer

\startbuffer[MyText]
      \framed[align=normal,frame=off]{\input{tufte}}%

seams this code means to put a hidden text with same size behind metapost
shape.
but it does not work properly for me (current version: 2024.04.01 08:59)
and produce empty page but with searchable hidden text.
also when i edit the code and replace metapost part like this:

\startMPcode
 draw lmt_outline [
 kind = "outline",
 text = "\getbuffer[MyText]",
  ]
 withcolor red
  ;
\stopMPcode

it produces a selectable hidden text on top of body and red text that drawn
by metapost below of that.

How can this problem be solved?

Thank you so much for the sample examples
it would be great to also make text select able in output pdf
the third example currently does not work. did you mean you will add

I've found my original file and the image is as Hraban says below. The 
code is the original in the post I quoted  and gives a green background 
with shaded colours in the text.
