Easier deletion of file paths in prompt

What feature would you like to see?

When I use @ to reference a file path, sometimes I select the wrong one via autocomplete. I would like these to be tokenized so that I can delete them with one backspace, or one alt-backspace. It currently takes an indeterminate number of strokes to delete an incorrect path, making it troublesome to correct.

Alternatively, a way to undo text entry would also solve this!
