Selecting and performing contextual actions via user interface objects

A system, comprising:

• at least one processor;
• at least one processor-readable medium, communicatively coupled to the at least one processor, and that stores at least one of processor-executable instructions or data, which when executed by the at least one processor causes the at least one processor to:
• cause a presentation of a graphical representation of a user interface comprising at least a first source object representation that represents a first source object and a first receiving object representation that represents a first receiving object;
• in response to a first drag operation that drags the first source object representation or an indicator that represents a position of a pointer, the pointer with which the first source object representation was selected, in at least a defined proximity of the first receiving object representation:
• determine which, if any, of a number of actions associated with the first receiving object can be performed on the first source object;
• and
• for each action that it is determined can be performed on the first source object, cause a presentation of a respective drop socket spatially at least overlapping or encompassed by the first receiving object representation, each drop socket having a respective boundary and responsive to a deselection of the first source object representation with the first source object representation or the indicator at least partially within the respective boundary of the drop socket to cause the respective action to be performed on the first source object.
