preshift

Before a shift (in various senses).

The factory workers in Plant 2 would stop at Uncle Nancy’s for preshift pick-me-ups, and the executives at Maytag headquarters down the street would come for lunch.

To shift in advance.

We preshifted the game sprites to avoid having to redraw them at different positions during gameplay.

A shift performed in advance.

[…] and the preshifts required to move the rectangle up one, right two or up one, left two.
