One thing to add though, some keyers f7 EVERYTHING automatically (whether they need to or not) without really checking, defeating the purpose of the suggestion lists. Just check the entry and make sure it's correct before whacking the f7 key.
The things to really watch are the entries that will be repeated dozens of times on a page. One error multiplies many times.
In particular
Slave Owners' names (slave manifests)
Street names (
Sands)
Surnames (Jacksonville and
Sands)
