6. The method according to claim 1 , wherein the first user interface mechanism and the second user interface mechanism are a first state and a second state, respectively, of a single user interface mechanism; wherein the method further comprises: changing the state of the single user interface mechanism from the first state to the second state in response to the activation of the first user interface mechanism; changing the state of the single user interface mechanism from the second state to the first state in response to the activation of the second user interface mechanism.
1. A method for presenting information, the method comprising the acts of: presenting an input expression on a workspace associated with a computational software application; presenting on the workspace a result that is an evaluation of the input expression by the computational software application, while presenting on the workspace the input expression; presenting on the workspace a first user interface mechanism associated with the input expression, while presenting on the workspace the result; hiding on the workspace the input expression, while presenting on the workspace the result, in response to an activation of the first user interface mechanism, wherein hiding the input expression reduces the size of the workspace as compared to when both the input expression and the result are presented on the workspace; presenting on the workspace a second user interface mechanism associated with the input expression; and presenting on the workspace the input expression in response to an activation of the second user interface mechanism, while presenting on the workspace the result.
