Only if it is a very hard text that I have to move slowly thru. For normal reading, no not at all. If I am trying to read something faster than is comfortable, I will periodically emphasize the thing, the idea, behind a key word, so I am more likely to remember it at the useful time. Not verbal and there are many many times when I can describe the thing but not recall the normal word. Like the flat thing with keys in it instead of keyboard. Or even weird quasi-synonyms that serve to muddy the waters as far as sharing my thoughts with others goes.
