Slue (American) Great many.

A large number

1. To turn (as a telescope or a ship's spar) about a fixed point that is usually the axis
2. To cause to skid; veer
3. To turn, twist, or swing about; pivot
4. Skid

The rate at which the output voltage swings from off to on and vise versa. Higher slew rates usually generate too much electrical noise. Slew rate control is a feature in many CPLDs that adjusts the slew rate of specified outputs allowing optimization between speed and the noise generated by sharp output transitions.

The maximum rate of change a power supply output can produce when subjected to a large step response or specified step change.
