well as they are key combinations, you'd need an alias to open a com object, i use someones that i got from here, i can't remember who's it is but credits to whoever they are smile

Code:
 alias sendkeys {
  var %a = sendkeys $+ $ticks
  .comopen %a WScript.Shell
  if !$comerr {
    var %b = $com(%a,SendKeys,3,bstr,$1-)
    .comclose %a
    return %b
  }
  return 0
} 


then i used like ..
alias editor { //sendkeys % $+ r }

alias colours { //sendkeys % $+ k }

alias options { //sendkeys % $+ o }
