[moneydance] Howto safely delete mistakenly downloaded transactions?

[Larry Alkoff]

I would like to know how to safely delete some transactions mistakenly 
downloaded to the wrong account or to "test" accounts.

In one case I downloaded transactions from an _investment_ account that 
went into my joint _checking_ account.  How that happened I know not.

In the other case I downloaded transactions from the same _investment_ 
account into a "test" investment account.  When I subsequently deleted 
the "test" account other investment accounts were affected and the 
balances were thrown off.  In this case, MD gave me this warning:

Delete: Schwab_bad
The account you would like to delete either contains transactions
or is referenced to one or more reminders.
Deleting this account will remove all transactions
and reminders that reference this account.
If you would like to delete this account, enter 'yes'
in the box below.

How can I delete this account without changing transactions in other 
accounts?

In the case where the same stock transaction has been down to two 
accounts, how would the transaction in the "correct" account be affected 
by deleting the "test" account?
