By right-clicking on any category there is an option to open a ledger for that category. You can also double-click on the category. When this option is selected KMyMoney will display a ledger with all the transactions for the selected category. This allows you to quickly review all the transactions in detail for the selected category. You can then right-click on any transaction to obtain additional details about the specific transaction ultimately allowing any editing that may be required. Note that you cannot edit a transaction in the Category ledger; you need to switch to the ledger display for the other account, using one of the selections in the popup menu when you right click on the transaction.
