• When you delete a transaction, Quicken removes the transaction from the register and recalculates all subsequent balances. If you need to retain a record of the transaction, consider voiding it instead.
• You can restore your most recently deleted transaction for any non-investment account by choosing Edit menu > Transaction > Undo Delete. You must perform the undo within the same Quicken session and from the same account from which the transaction was deleted. If several transactions were selected and deleted in one operation, Undo Delete restores all of them.
• Use CTRL+click or SHIFT+click to select multiple transactions in an account register (does not work in an investment transaction list).
• If you delete a transaction that includes a transfer, Quicken deletes the transfer from both the source and destination accounts.
• You can protect transactions from being deleted accidentally by requiring a password before opening a file or before changing transactions entered on or before a certain date.
