Yes. Use StrongED and drag in a script like this, with the
replace table appropriately modified (presuming you have !lua
filerbooted).

  #! lua
  -- multiple search and replace
  local replace = { -- edit this table
  ["seperate"] = "separate";
  ["supercede"] = "supersede";
  ["kernal"] = "kernel";
  ["old rubbish"] = "snappy phrase";
  }
  -- search for string in square brackets, replace with
  -- string between equal sign and semicolon.
  local transform = \(x,y)
     for old,new in pairs(y) do
       x = x:gsub(old,new)
     end -- for
     => x
   end -- function
  local f = io.open(arg[1],"r")
  local s = f:read "*all"
  f:close()
  io.write(transform(s,replace))
