1. A computing system comprising:
- a touch screen;
one or more processing devices; and
one or more computer-readable storage media comprising computer-executable instructions that, when executed by one or more processing devices, cause the one or more processing devices to;
identify a finger that is in tactile contact with the touch screen;
select an individual symbol from a plurality of symbols based on the identified finger;
after the individual symbol is selected, determine whether another finger that comes into tactile contact with the touch screen concurrently with the finger is a thumb or a different finger;
in first instances when the another finger is not the thumb, change the individual symbol to another individual symbol from the plurality of symbols; and
in second instances when the another finger is the thumb, change the individual symbol to a corresponding capitalized symbol.

Abstract
This document describes tools associated with symbol entry control functions. In some implementations, the tools identify a first finger that is in tactile contact with a touch screen. The first finger can select a subset of symbols from a plurality of symbols that can be entered via the touch screen. The tools can also identify whether one or more other fingers are in concurrent tactile contact with the first finger on the touch screen. The tools can select an individual symbol from the subset based on whether the one or more other fingers are in concurrent tactile contact with the first finger on the touch screen.

10. A method performed by a computer processing unit, the method comprising:
-
determining an identity of a finger that is in tactile contact with a touch screen; selecting an individual symbol from a plurality of symbols based on the identity of the finger; after the individual symbol is selected, determining whether another finger that comes into tactile contact with the touch screen concurrently with the finger is a thumb or a different finger; in first instances when the another finger is not the thumb, change the individual symbol to another individual symbol from the plurality of symbols; and in second instances when the another finger is the thumb, change the individual symbol to a corresponding capitalized symbol. - View Dependent Claims (11, 12, 13, 14)

15. A hardware computer-readable storage media storing instructions which, when executed by a computer processing unit, cause the computer processing unit to perform acts comprising:
-
determining an identity of an individual finger that is in tactile contact with a touch screen; selecting an individual symbol from a plurality of symbols based on the identity of the individual finger; after the individual symbol is selected, determining another identity of another individual finger that comes into tactile contact with the touch screen concurrently with the individual finger, the another identity being one of a thumb, an index finger, a middle finger, a ring finger, or a little finger; in first instances when the another identity is not the thumb, change the individual symbol to another individual symbol from the plurality of symbols; and in second instances when the another identity is the thumb, change the individual symbol to a corresponding capitalized symbol. - View Dependent Claims (16, 17, 18, 19, 20)
