OmniFocus has a feature that allows you to "clip" selected text from other applications and make it into a new action in your OF database. (You hit a keyboard shortcut that you define; the selected text becomes a new action in your OF database.)

The "Clipping material from other applications" page in OmniFocus' help menu material can help you set up the clipping feature if you aren't already using it.

Does that help?
