"When's Alex coming over? Did you pick up the cake? Will you be ready by 5pm?" Answering a series of questions in a comprehensible way in a fast-paced WhatsApp chat can be tricky.

The same goes when you refer back to a previous message but don't make that clear to the other person. Misunderstandings and confusion are just waiting to pounce in such situations.

Messenger app makers are trying to help us, however, with a handy trick: By swiping right (or, depending on your phone, left) on the old text you'd like to cite, you can then write new text, and they both will be sent to the person together.
