Abstract: In an example method, a user interface is presented by a device on a touch sensitive surface of the device. The device presents a keyboard image on a touch sensitive surface of the device. The device then receives a first touch input selecting a key of the keyboard image and responsive to receiving the first touch input, displays a primary character associated with the selected key. While maintenance of physical contact is detected by the touch sensitive surface, the device receives a touch gesture starting at the key of the keyboard image and continuing in a diagonal direction along a face of the key. Responsive to receiving the touch gesture, the device displays an alternative character associated with the selected key.

Abstract: In an example method, a user interface is presented by a device on a touch sensitive surface of the device. The user interface includes a first portion for displaying a sequence of code and a second portion for displaying suggested bracketed functions. The device receives a first touch gesture dragging a suggested bracketed function from the second portion to the first portion of the user interface. Responsive to receiving the first touch gesture, the suggested bracketed function is inserted into the sequence of code. The bracketed function encloses at least a portion of the sequence of code. The device receives a second touch gesture dragging an end bracket associated with the inserted bracketed function. Responsive to receiving the second touch gesture, the sequence of code is modified such that the bracketed function encloses an additional portion of the sequence of code.

Abstract: In an example method, a user interface is presented by a device on a touch sensitive surface of the device. The device receives a first touch input selecting a numeral presented in the user interface. Responsive to receiving the first touch input, a numeric keypad interface and a display element are presented. The device receives a second touch input selecting the display element. Responsive to receiving the second touch input, a rotary interface including the display element is presented. While the user is maintaining physical contact with the touch sensitive surface, the device receives a rotational touch gesture dragging the display element about the rotary interface. Responsive to receiving the rotational touch gesture, the numeral is modified.

Abstract: In one embodiment, an improved programming system and language for application development is provided that combines elements of the C and Objective-C languages without the constraints imposed by a requirement to maintain compatibility with the C language. The language provides the functionality of the C language compatibility in certain areas to improve the inherent safety of software written in the language. The new language includes default safety considerations such as bounds and overflow checking.
