I believe the way thought and movement work together are quite similar to the way thought works when it has no corresponding overt motion to express the affects of a thought. Thought has no proprioception built into it, but the judgment of movment does. But proprioception only senses differences, it is not an absolute measuring device.
Intention is responding, whether it has a word attached to it or not. Some people translate action or reaction into language before they move. It makes their movements delayed. Decision is the first part of response, but there can also be a habit that recognizes and handles reactions too.
As a technique, if you think any movement through step by step, you'll detour the "trigger" word and the corresponding sets of habits - whether they have words or not.
