These are for use in Modefiles.

Courtesy forbids any but the most elliptic reply. For Ctrl-drag to
the "Apply" smarticon to work you need something in a scripting language that
your copy of StrongED understands. Unfortunately StrongED's functions
do not qualify. Try this Lua script instead

#! lua
-- GCW 06/04/2012
local write,lines in io
local replace = { [" "] = ".", ["\160"] = "\143" }
local find = "[%s\160]"
for line in lines(arg[1]) do
  write((line:gsub(find,replace)),"\182\n")
end -- for
