1. A method of enabling user interaction with computer software running in a computer system via:
a printed interface surface containing information relating to the computer software and including coded data indicative of a text field, the coded data comprising a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark positions; and
a sensing device which, when placed in an operative position relative to the interface surface:
senses at least some of the coded data,
generates indicating data indicative of the text field, and
generates movement data, the movement data being indicative of the sensing device's movement relative to the interface surface;
the method including the steps of, in the computer system:
(a) receiving the Indicating data from the sensing device;
(b) receiving to movement data from the sensing device;
(c) identifying the text field from the indicating data; and
(d) operating the computer software at least partly in reliance on the movement data and in accordance with instructions associated with the text field.
