A handheld electronic device has a display screen and uses a keypad as an input means. The keypad has multiple keys, at least some of which are two-stage keys such that a light touch indicates one function and a full depression indicates another function. The device is programmed so that consecutive light touches of at least two adjacent keys indicates a desired navigation function on the display screen corresponding to a direction of the consecutive light touches. An additional selection key or keys, such as a Shift, Alt or Function key or the like, may be used to vary the default navigation action indicated by the consecutive light touches.
