Drag & Duplicate Keyboard Shortcut?

I do a lot of right click > copy > paste when I eat the same ingredient multiple times in a day, and all the clicking gets cumbersome. In tools like Photoshop I frequently use the feature where you click and hold an item, hold "Alt", then drag the item, and a duplicate is created that you can drag wherever you want. It'd be amazing if I could select 1 or multiple food entries and then, with one keyboard swipe, duplicate & drag another instance of the food wherever i needed it, with no manual copying/pasting required! Or even if there were just copy/paste keyboard shortcuts.
