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 that are not apparent in the FIG. 1 view, the 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 the FIG. 1 view, the bottom view is identical.
The portions of the user interface shown in dot-dot-dash 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 indicate a change in color.
