I am running fdisk on a device and I'm trying to list the supported partition types. The problem is that it immediately scrolls off the screen and I can't see it.
I was using the latest Fedora on someone's Macbook yesterday and fdisk would pause with a : (like the output of less and allow scrolling or q to break from the output.
I am running CentOS 7.5 in text mode from a minimal install on a VGA monitor connected through an HDMI adapter to the system.
Is this a limitation of my terminal, being in text mode (fdisk on the Macbook was run in a terminal on GNOME), the fact that it's an older version of fdisk, or something else entirely?

doesn't Shift-PageUp work anymore?

That's a thought - but he's using a MacBook (take a look at the keyboard). If it's recent hardware: no, he doesn't have that key :-)

Oops. But If Fn+Shift+Up doesn't work instead of Shift+PageUp, it's a bug.

Most terminal emulators have scrollback.

The latest Fedora is newer by a year or two than the latest RHEL 7. A newer fdisk is a possibility.
You could work around this by using script to capture the output, and using less on the resulting typescript file (running fdisk and less separately of course).
You could also use the scrolling feature in screen or tmux, but those typically are not installed initially on a Linux system — they're optional/extra features.

He's talking Fedora and CentOS - both do that.
