hotkeying
Remember that F3 = SEARCH IN CURRENT BASE is probably most effective as your first hotkey search on a heading you're trying to verify or add. It gives you a response of all occurrences of your heading and nearby ones. Especially good for subject headings. It does tell you if there's an authority record for the whole string (in the codes to the right) and you can "expand" to see the authority record. While the text-strings are good for repeated text, they do not replace a hotkey and selecting the heading from the heading browse.
