Transaction History 

In the Accounting section, double click on an account.

You can optionally specify the date range at the top.  Asset accounts default to entire history.  Expense and revenue accounts default to only the current year.  You can also search for any text which is in the Chk# column or the Memo.  A search on amount will search both the debit and credit columns.

Click Add Entry, or double click on an existing transaction to Edit the Transaction.

Asset accounts will have a Reconcile button available in the main toolbar to reconcile monthly bank statements.
