Here is the paragraph I blogged on Monday:

There will be times when we will not be able to consciously pray because we rightly have to concentrate on the task that is before us. The prayer of intention is a way of offering our work or present task as a prayer, asking that the quality and care with which we attend to it may itself be a prayer

In answer to your comment Jack, it does seem as if the task could be totally unrelated to the prayer.
