[GNC] find AND REPLACE?

[Paul Costan]

I am looking for the command(s) or work-around to accomplish what I used 
to use in Quicken as Find and Replace.  Specifically, after downloading 
multiple months of transactions from my credit union into a simple 
checkbook ledger, I could use the Quicken "find" to select all 
transactions with description "Safeway" and then select from them to 
"replace" the category to "Groceries". I'm good in Gnucash up through 
the Find part, can't figure out how to easily set the Account without a 
lot of keystrokes. Didn't see anything in the manual/help/faq.  
Suggestions? Thanks.
