How to scroll in the Terminal app "top"?
I've read the info page, but I can't find any way to scroll the list in top.
Maybe there is no way to scroll?... but there must, at least, be some way to filter the list, and I can't find that either.
How do I display line-entries which are off the page?

I have only one suggestion: use htop instead.
sudo apt-get install htopThe point of the "TOP" program is to tell you which processes are using the most resources or are at the TOP of the list.
For a full process list use "ps":
ps auxYou can filter it with "grep":
ps aux | grep firefoxThis is a bit old, but I'm finding that I can scroll top just fine in version 3.3.9 (Default on Ubuntu 14.04)
If you hold the down arrow, it'll look like you aren't scrolling, but just keep holding. For each repetition, I believe there is a marker that is moving down, row by row (not visible) and when it hits the bottom the window scrolls down.
Also the PageUp and PageDown keys work a bit faster.
Indeed, the up and down arrow keys will scroll through top on newer versions, specifically at least on the version of top that comes with Ubuntu 16.04.2 (procps-ng version 3.3.10).
But if the arrow keys don't work to scroll for you, it could just be an issue with your terminal emulator.
Take a look at the top man page:
Lastly, some of top's screens or functions require the use of cursor motion keys like the standard arrow keys plus the Home, End, PgUp and PgDn keys. If your terminal or emulator does not provide those keys, the following combinations are accepted as alternatives:
key equivalent-key-combinations Up alt + \ or alt + k Down alt + / or alt + j Left alt + < or alt + h Right alt + > or alt + l (lower case L) PgUp alt + Up or alt + ctrl + k PgDn alt + Down or alt + ctrl + j Home alt + Left or alt + ctrl + h End alt + Right or alt + ctrl + l
So if the up and down arrow keys don't work for you (make sure you hold them down, as deto said), try pressing alt + \, alt + /, alt + k and alt + j.
Note that this section of the man page does not exist on my RHEL 6.6 machine, which has procps-ng version 3.2.8 (you can see the version number with top -v), and so that version of top does not appear have any scrolling capability.
