15. A method according to claim 12 , further comprising: prior to determining that at least the portion of the second user input in the imprecise syntax corresponds to the second instruction in the precise syntax, including, with one or more computing devices, at least the portion of the second user input in the imprecise syntax in the workspace document displayed on a display device; wherein simultaneously displaying at least the portion of the second user input in the imprecise syntax and the second instruction in the precise syntax on the workspace document comprises displaying, on the display device, a display portion at a location in the workspace document at which at least the portion of the second user input in the imprecise syntax was displayed prior to determining that at least the portion of the second user input in the imprecise syntax corresponds to the second instruction in the precise syntax; wherein the display portion simultaneously includes the at least the portion of the second user input in the imprecise syntax and the second instruction in the precise syntax.

A method according to claim 12 , further comprising: prior to determining that at least the portion of the second user input in the imprecise syntax corresponds to the second instruction in the precise syntax, including, with one or more computing devices, at least the portion of the second user input in the imprecise syntax in the workspace document displayed on a display device; wherein simultaneously displaying at least the portion of the second user input in the imprecise syntax and the second instruction in the precise syntax on the workspace document comprises displaying, on the display device, a display portion at a location in the workspace document at which at least the portion of the second user input in the imprecise syntax was displayed prior to determining that at least the portion of the second user input in the imprecise syntax corresponds to the second instruction in the precise syntax; wherein the display portion simultaneously includes the at least the portion of the second user input in the imprecise syntax and the second instruction in the precise syntax. 16. A method according to claim 15 , further comprising, in response to a user selection of the second instruction in the precise syntax in the display portion, removing at least the portion of the second user input in the imprecise syntax from the workspace document such that the second user input in the imprecise syntax is not displayed on the display device.
