How about

  require("keydefs");                  % standard jed lib file
  autoload("get_word", "txtutils");    % jedmodes.sf.net/mode/txtutils
  definekey("get_word()", Key_Alt_Down, "Mini_Map");

in your jed.rc?

Indeed I would prefer this behaviour. Ideally, the "init" string should
be marked as a "transient" visible region (as regions with wmark or
cuamark). The user gets a feedback that deleting would not just delete
a character and any non-region operation would pop the mark.

with cuamark.sl you can try the ugly workaround:

 % Replace a ^<somechar> sequence with the corresponding control character
 % analogue to setkey()
 % Rather crude and not fail-proof
 define decode_ctrl_chars(str)
 {
    variable a = bstring_to_array(str);
    a[where(a == '^')+1] -= 64;  % shift to start at '^@'
    return array_to_bstring(a[where(a != '^')]);
 }


 buffer_keystring(decode_ctrl_chars(Key_Home));
 buffer_keystring(decode_ctrl_chars(Key_Shift_End));
 $0 = read_mini("Prompt:", "dflt", "init");
 
For some strange reason, the key_hooks used on cuamark do not seem to
work with this workaround so the region is not "transient". However, with
the cua bindings Key_BS will delete a "visible region" so it kind-of
works.

I think it is better to implement this in a separate file. Modifiying a
standard file like mini.sl means you will always have to update it with
new releases.
