What counts as an update?

For the purposes of the Autosave frequency option, the following are counted as one update:

Overtyping the contents of a record

Changing the contents of a record by overtyping, regardless of the number of characters changed, is counted as a single change. If you press Enter and then overtype your changed record again, this is counted as a second change.

Using a prefix command that alters record data

A prefix command that alters data, such as ">" (the command for shift right), is counted as a single change. Use of a prefix command is counted as only one change, even if the command is used to alter multiple records.

The CHANGE or RCHANGE primary command

When you issue the CHANGE or RCHANGE primary command without the ALL operand, the command counts as one change for each record it actually changes.
