in response to detecting when in the normal mode a user's digit at a location hovering over but not touching the touch screen while plural discrete items are being displayed in the normal mode, entering a zoom mode; in response to entering the zoom mode, causing zooming of the displayed plural discrete items; when in the zoom mode, responding to detection of movement of the user's digit to a different hover location over the touch screen; and causing movement of a cursor, pointer or marker as the location of the hover location changes or a touch input is detected. ### Claim 2 (depends on 1) A method as claimed in claim 1, wherein the discrete items are text characters. ### Claim 3 (depends on 2) A method as claimed in claim 2, comprising depositing a cursor at the hover location or the location of the touch input in response to the detected change of the hover location or detected touch input. ### Claim 4 (depends on 1) A method as claimed in claim 1, wherein the discrete items are icons. ### Claim 5 (depends on 4) A method as claimed in claim 4, comprising selecting an icon at the hover location or the location of the touch input in response to the detected change of the hover location or detected touch input. ### Claim 6 (depends on 1) A method as claimed in claim 1, comprising responding to detecting removal of the user's hovering digit by reverting to the normal mode and causing zooming out of the plural discrete items. ### Claim 7 (depends on 1) A method as claimed in claim 1, comprising responding to detecting removal of the touch input by reverting to the normal mode and causing zooming out of the plural discrete items. ### Claim 8 (depends on 1) A method as claimed in claim 1, comprising responding to detecting removal of the user's hovering digit by reverting to the normal mode and causing zooming out of the plural discrete items to a zoom level that existed at the time of entering the zoom mode. ### Claim 9 (depends on 1) A method as claimed in claim 1, comprising responding to detecting removal of the touch input by reverting to the normal mode and causing zooming out of the plural discrete items to a zoom level that existed at the time of entering the zoom mode. ### Claim 10 Apparatus, the apparatus having at least one processor and at least one memory having computer-readable code stored thereon which when executed controls the at least one processor: in a normal mode, causing display of plural discrete items on a touch screen; in response to detecting when in the normal mode a user's digit at a location hovering over but not touching the touch screen while plural discrete items are being displayed in the normal mode, entering a zoom mode; in response to entering the zoom mode, causing zooming of the displayed plural discrete items; when in the zoom mode, responding to detection of movement of the user's digit to a different hover location over the touch screen; and causing movement of a cursor, pointer or marker as the location of the hover location changes or a touch input is detected. ### Claim 11 (depends on 10) Apparatus as claimed in claim 10, wherein the discrete items are text characters. ### Claim 12 (depends on 11) Apparatus as claimed in claim 11, wherein the computer-readable code when executed controls the at least one processor to deposit a cursor at the hover location or the location of the touch input in response to the detected change of the hover location or detected touch input. ### Claim 13 (depends on 10) Apparatus as claimed in claim 10, wherein the discrete items are icons. ### Claim 14 (depends on 13) Apparatus as claimed in claim 13, wherein the computer-readable code when executed controls the at least one processor to select an icon at the hover location or the location of the touch input in response to the detected change of the hover location or detected touch input. ### Claim 15 (depends on 10) Apparatus as claimed in claim 10, wherein the computer-readable code when executed controls the at least one processor to detect removal of the user's hovering digit by reverting to the normal mode and causing zooming out of the plural discrete items. ### Claim 16 (depends on 10) Apparatus as claimed in claim 10, wherein the computer-readable code when executed controls the at least one processor to detect removal of the touch input by reverting to the normal mode and causing zooming out of the plural discrete items. ### Claim 17 (depends on 10) Apparatus as claimed in claim 10, wherein the computer-readable code when executed controls the at least one processor to respond to detecting removal of the user's hovering digit by reverting to the normal mode and causing zooming out of the plural discrete items to a zoom level that existed at the time of entering the zoom mode. ### Claim 18 (depends on 10) Apparatus as claimed in claim 10, wherein the computer-readable code when executed controls the at least one processor to respond to detecting removal of the touch input by reverting to the normal mode and causing zooming out of the plural discrete items to a zoom level that existed at the time of entering the zoom mode. ### Claim 19 A non-transitory computer-readable storage medium having stored thereon computer-readable code, which, when executed by computing apparatus, causes the computing apparatus to perform a method comprising: in a normal mode, causing display of plural discrete items on a touch screen; in response to detecting when in the normal mode a user's digit at a location hovering over but not touching the touch screen while plural discrete items are being displayed in the normal mode, entering a zoom mode; in response to entering the zoom mode, causing zooming of the displayed plural discrete items; when in the zoom mode, responding to detection of movement of the user's digit to a different hover location over the touch screen; and causing movement of a cursor, pointer or marker as the location of the hover location changes or a touch input is detected.
