The ornamental design for an alphanumeric input keyboard, as shown and described.

The sole drawing FIGURE is a front view of an alphanumeric keyboard showing my new design.

The design shown has all characters on the same level in a flat plane with no depth or contour.

The portions of the alphanumeric input keyboard shown in dot-dot-dash broken lines form no part of the claimed design. The drawing is lined for color.

The evenly spaced horizontally parallel broken lines shown in various locations indicate a change in color.
