[GNC] Beginner use case: Checking, Savings, Credit Card = how do I correlate a transaction in Checking Withdrawal to Savings Deposit or Credit Card payment?

[Bruce Griffis]

I'm trying to figure out the very basics of managing a checking account, 
savings account and credit card in GnuCash. I downloaded a csv of all 
checking transactions for a year and imported them. They look good and 
match up with my check register. Then I downloaded my savings for a year 
into a savings account in GnuCash. Finally, I downloaded a csv of credit 
card transactions for a year and imported into a liabilities/credit card 
account.

So, in my checking account, I see a transfer to savings. This is marked 
imbalanced.

In my savings account, I see a deposit maybe the same day and the same 
amount. This is marked imbalanced.

If I open my checking account register and changed the destination 
account from imbalanced to savings, then I see that transaction pop up 
in my savings register. I now have two transactions of the same amount 
and possibly the same day in my savings register. Would I delete the 
duplicate entry I got when I downloaded the csv? Or what do I do to show 
that my checking transfer out transaction is the same as my savings 
increase transaction?

And the same with my credit account. I see a payment out of checking to 
SuperBigBank Mastercard. In the credit card, I see a payment. Both are 
imbalanced. If I change the checking transaction to show it goes to my 
credit card, I now see two transactions in my credit card register. 
Would I simply delete the duplicate entry? Or how do I show that they 
are the same transaction?
