45. The method of claim 43, further including: when the received input is a second indicator, navigating a right operand of the computational construct.
43. A method in a computer for navigating through a representation of a computational construct, comprising: receiving input from a user; when the received input is a specification of binary operator, setting the computational construct to be a right operand of the binary operator; and when the received input is a first indicator, setting a current selection to a selection of a parent computational construct of the computational construct by applying the first indicator to the parent computational construct.
