Robert,
Thanks. If now you can find the cause why the line is not hilited
permanently...
I don't see it

how to import an icon from elswhere?
I cannot find the good one in the build-in iconlist
Import image or copy-paste should do. An icon is just an image of certain size.

OK

2.
In a listbox-field I want the selectedt line be hilited permanently
until a next line is clicked. Now the the line is hilited for the
tihe mouse is pressed down.
Make it a list field (lock it and set the autohilite to true). However, I suspect that you aleady have that and the hilite disappears on mouseUp because of something in the script.


RIGHT,
THIS IS THE SCRIPT THAT INTERVENES
LIKE YOU THOUGHT, BUT I DON'T SEE IT:

on fillfield
  set the lockscreen to true
  get cardnames of this stack
  put (number of lines of it) into Lastline
  repeat with i = 1 to Lastline
    put quote&char 1 to 32 of line i of it&quote &","after list
  end repeat

  ---    LIST TO ALPHABETIC TEXTLINES
  set the foregroundcolor of field "content" to black
  if last char of list="," then
    clear last char of list ------------komma weg
  end if
  sort items of list -----------------alphabetisch
  repeat with  i = 1 to Lastline
    put item i of list &linefeed after tempfield
  end repeat

  ------        CLEAR QUOTES
  replace quote with "" in tempfield
  set text of field "content" to tempfield
  set the listbehavior of fld "content" to true
end fillfield

You may set the hilitedLines to restore the selection at the end of the handler (cf script below).


DON"T SEE WHAT YOU MEAN;

3.
In the same listboxfield I want to choose a line just by pressing down
a key: f.i. the R to get the first line beginning with a R.
The only way to choose now is with mouse or arrow-keys.

place the following handler on the card (untested but fully commented):

THIS WORKS FOR ME

on keyDown theKey
  set the cursor to watch
  -- transfer fld "content" to var
  get fld "content"
  -- preserve current selection
  put the hilitedlines of field  "content" into h
  -- preset line counter
  put 1 into s
  -- loop through lines
  repeat for each line t in it
    -- increase counter (we are purposefully 1 off)
    add 1 to s
    -- escape if condition met
    if char 1 of t is theKey then exit repeat
  end repeat
  -- check if we found a match
  if s > the number of lines of it then
    -- no match so restore earlier selection
    put h into s
    -- tell user that no match found
    beep
  else
    -- correct line reference
    subtract 1 from s
  end if
  -- update display if a line is selected
  if s is not empty then
    -- set the hilite
    set the hilitedLines of fld "content" to s
    -- scroll the field accordingly (12 is line height)
    set the scroll of fld "content" to (s-1)*12
  end if
end keyDown
