Abstract

A keyboard number lock may be automatically transitioned in response to the detection of the selection of a text entry box. In particular, when a text entry box is selected, the keyboard may automatically be transitioned to the number lock state to provide numerical entries when particular keys are operated.

Claims

1. A method comprising:

detecting a selection of a text entry box; and

in response to the detection of a selection of a text entry box, automatically recognizing a moveable keystroke from a numeric keypad section of a keyboard with moveable keys as numeric key entry, said recognizing without user movement of another moveable key on the keyboard, and automatically, in response to said recognizing, initiating a numeric mode of the keyboard wherein keystrokes are recognized as numeric entries rather than cursor controls, the numeric keypad section including a plurality of moveable number keys arranged in rows and columns.

2. The method of claim 1 wherein automatically recognizing certain key entries as numeric key entries includes automatically recognizing, in software, the certain key entries as numeric key entries without changing a state of a keyboard number lock when the selection of a text entry box is detected.

3. The method of claim 1 wherein detecting the selection of a text entry box includes detecting placement of a cursor in a text entry box prior to entering information in the text entry box.

4. The method of claim 3 including caching keystrokes to enable entry of numeric information in said text entry box upon detecting the selection of the text entry box.

5. The method of claim 3 including detecting the removal of the cursor from the text entry box and in response, automatically recognizing the certain key entries as non-numeric key entries.

6. The method of claim 1 wherein automatically recognizing certain key entries as numeric key entries includes automatically changing a state of a keyboard number lock, in hardware, to a numeric entry mode.

7. An article comprising a medium storing instructions that enable a processor-based system to:

detect selection and deselection of a text entry box based on cursor placement in or out of the text entry box respectively; and

in response to the detection of the selection of the text entry box, automatically place a numeric keypad section of a keyboard in a numeric mode, and in response to the detection of the deselection of the text entry box automatically place the keypad section in a cursor control mode, the automatic placement of the keypad section in the numeric mode without user operation of a key on the keyboard.

8. The article of claim 7 further storing instructions that enable a processor-based system to automatically change a state of a keyboard number lock in response to the detection of the selection of a text entry box.

9. The article of claim 8 further storing instructions that enable the processor-based system to automatically change the state of the keyboard number lock to a non-numeric entry mode in response to the deselection of a text entry box.

10. The article of claim 8 further storing instructions that enable the processor-based system to receive a web page including a text entry box and automatically change the state of a keyboard number lock in response to the selection of the text entry box.

11. The article of claim 7 further storing instructions that enable a processor-based system to detect the placement of a cursor in a text entry box prior to entering information in the text entry box.

12. The article of claim 7 thither storing instructions that enable the processor-based system to cache key strokes to enable entry of numeric information in said text entry box upon detecting the selection of the text entry box.

13. A processor-based system comprising:

a processor;

a keyboard coupled to the processor, the keyboard having a numeric keypad section with a plurality of keys that selectably function in a numeric entry mode or a non-numeric entry mode, the keyboard also having a mode-controlling key that, if actuated, causes the plurality of keys to selectably function in the numeric entry mode; and

a storage coupled to said processor, said storage storing instructions that enable the processor to detect selection of a text entry box and in response to the detection of a selection of a text entry box, to recognize a moveable keystroke as numeric entries without user movement of the mode-controlling key, and automatically, in response to said recognizing, transition to a numeric mode of the keyboard wherein keystrokes are recognized as numeric entries rather than cursor controls, the numeric keypad section including a plurality of moveable number keys arranged in rows and columns.

14. The system of claim 13 wherein said storage stores instructions that enable the processor to detect placement of a cursor in a text entry box as an indicator of the selection of the text entry box.

15. The system of claim 13 wherein said storage stores instructions that enable the processor to cache key strokes to enable entry of numeric information in said text entry box upon detecting the selection of the text entry box.

16. The system of claim 13 wherein said storage stores instructions to automatically change a state of the keyboard number lock in response to the detection of the selection of a text entry box.

17. The system of claim 16 wherein said storage stores instructions that enable the processor to automatically change the state of the keyboard number lock to a numeric entry mode in response to the detection of the selection of the text entry box.

18. The system of claim 16 wherein said storage stores instructions that enable the processor to detect deselection of a text entry box and in response, automatically change the state of a keyboard number lock, said detection of deselection based on removal of a cursor from the text entry box.
