This bug hasn't seen activity in quite a while, and the pager is now disabled by default in Octave 4.4, closing. If there is still a problem in the current version of Octave please report it.

It works for me, so it's going to be difficult to debug. I expect that the problem is somehow related to Qt but this is just a guess.

I can offer two solutions:
a) you wait a bit; I will create a new dmg for 4.2rc2 which is going to use Qt5. Qt5 should have a lot less bugs on macOS.

b) you could disable the pager (which seems not too bad in a GUI environment):


This can be conveniently added to you ~/.octaverc.

I am experiencing the same issue. Paging works fine when I run the octave-cli ( /Applications/Octave.app/Contents/Resources/usr/bin/octave-cli ) in a terminal.

I am running 4.0.3 dowloaded from:

While preparing this comment the hung gui got this error (which may or may not be related)

This problem may be specific to macOS or to which packaging system you used to build and install Octave. Does the pager work correctly if you run octave-cli in a terminal? Did you install a binary package or use a package manager, which one? Adding sschoeps in cc.

Try `ones(100)` in the Command Window.

This will force a "(f)orward (b)ack (q)uit" pager prompt, but none of those keystrokes seem to have any effect.

Keystrokes appear onscreen, but we never get back to a `>> ` prompt.

Closing Octave GUI now is unresponsive, I have to CMD+ALT+ESC -> force-quit.

Pretty sure that this was working a few days back out-of-the-box.
