1. A method performed by a computing device comprising a display and an input device, the method comprising:

  • receiving inputs from the input device, the inputs having been inputted by interactions of a user with the input device;

    mapping the inputs to strokes, each stroke comprising a discrete unbroken line of input having any arbitrary shape in at least two-dimensions;

    recognizing command gestures to be invoked by the strokes by analyzing features of the strokes to map the strokes to the command gestures, the recognizing including analyzing features of the strokes to identify, as target strokes from among the strokes, all and only those strokes that are not straight lines and that consist of two substantially straight segments connected at respective ends thereof, wherein each target stroke is mapped to a same target command gesture;

    for each identified target stroke mapped to the target command gesture;

    invoking a same function, the function having an input parameter that selects options of the function; and

    determining a value for the parameter by determining whether an adjunct input from the input device was inputted in association with the target stroke, wherein the adjunct input is not part of the identified target stroke and is inputted substantially after initiation of the target stroke, wherein determining that an adjunct input was not inputted in association with the target stroke sets the parameter to a first value, wherein determining that an adjunct was inputted in association with the target stroke sets the parameter to a second value, wherein the first option is selected when the parameter is set to the first value, and wherein the second option is selected when the parameter is the second value.
