incantation n.

Any particularly arbitrary or obscure command that one must mutter at a system to attain a desired result. Not used of passwords or other explicit security features. Especially used of tricks that are so poorly documented that they must be learned from a [wizard]. "This compiler normally locates initialized data in the data segment, but if you [mutter] the right incantation they will be forced into text space."
