The ornamental design for a userinterface for a keyboard, keypad, or touchscreen, as shown and described.
FIG. 1 is a front view of a user interface for a keyboard, keypad, or touchscreen showing my new design;
FIG. 2 is a right side view thereof shown removed from its environment in order to show aspects of the design not apparent in FIG. 1, left side is identical; and,
FIG. 3 is a top view thereof shown removed from its environment in order to show aspects of the design that are not apparent in FIG. 1, bottom view is identical.
The portions of the user interface shown in dot-dot-dash broken lines, and the two characters shown in broken lines, are directed to environment and are for illustration only; they form no part of the claimed design.
The evenly spaced horizontally parallel broken lines shown in various locations in FIG. 1 indicate a change in color.
