A programmable device such as a smart phone allows a user an opportunity to make final corrections to textual data in a message after the user has instructed the device to send the message, but before transmittal of the message. The opportunity is temporary, to avoid impeding the flow of communication, and the textual data is transmitted unmodified if the opportunity to modify it is not accepted. Modifications made during the opportunity period may be used to adapt an autocorrect functionality of the programmable device.
