Because this is almost a tautology and so natural, Gmail makes going from one message to the next particularly easy. Sure, you can use the ‹ Newer and Older › links found on the navigation bars when you open a message in Gmail. But you can even more elegantly and efficiently employ the keyboard.
Go to the Next or Previous Message Quickly in Gmail
To jump to the next or previous message quickly in Gmail:
- Press j to go to the next (older) message.
- Press k to go to the previous (newer) message.
If you press K while reading the newest message (or J while reading the oldest message), Gmail will take you back to the view you started from.
