Unfortunately I am not the developer...
After all, never mind... The expression "Open in RegEdit" is not bad, but, like I wrote, at least three similar programs (TuneUp Registry Cleaner, Lavasoft Registry Tuner, RegVac Registry Cleaner) are using expressions as "Show Key" or "Go to Key" in the context menu, and that's clear for the user too.
But "the game is not worth the candle", so let's forget about it :)
