How do I delete a range of entrreis without doing them one at a time?
Are you asking about deleting transactions in a banking account register? Or in an investment account register? Or somewhere else? Quicken for Windows or Quicken for Mac?
In Quicken for Windows, in a banking account register you can delete multiple transactions by first selecting them, just like you would select block of files in a Windows File explorer view. Once you have selected transactions, right-click one of the selected transactions and choose Delete from the popup.
Do be sure to have or create a backup of your Quicken data file BEFORE you start making changes. If you make a mistake, you can restore the backup file.
