programatically click?

[Richmond]

on mouseUp
   click at line 5 of fld "FLIST"
end mouseUp

gives me this:

Type    click: expression is not a point
Object    Button
Line    click at line 5 of fld "FLIST"
Hint    Elephants

["Elephants" is the content of line 5 of fld "FLIST"]

this:

on mouseUp
    click at char 1 of line 5 of fld "FLIST"
end mouseUp

throws the same sort of error.
