Does "naDevDaq yIghoS" mean come here?

[torqey]

I tried to make a screen saver that would say, "Come back!" or "Come back on (the computer)!" I couldn't find that, so I created "naDevDaq yIghoS", or "Come here". Two questions: Did I get it right, and is there any way to say "Come back" instead of "Come here"? Thanks ahead of time

naDev is one of a few words that don't need -Daq, so naDev yIghoS would be enough. naDev yIghoSqa' would be "Come here again.".  But how about yIchegh! "Return!"

naDev is one of a few words that don't need -Daq,...

The Klingon Dictionary actually puts it more strongly: The nouns naDev here, pa' there, and Dat everywhere are inherently locative in meaning and never take the -Daq suffix.
