Scrolling the terminal without a mouse

I'm sure this has been asked before, but anytime I try scrolling using the arrow, page up/down keys and/or those in combination with ctrl, shift, alt, etc. It just types some odd combination of symbols into the terminal. Something like {`3|, though I don't remember exactly.

For example, this makes it impossible to see for example anything above the letter S when I check for all installed applications.

I am very new to Linux and I only know some of the basics and am trying to learn it. I've googled but nothing really helped me there.

Thanks in advance!

If you don't have a mouse available, better pipe that command output to less (the more modern version of more):

dpkg -i | less

This is made for keyboard use, unlike those graphical terminals' scroll bars.

See man less for all the key combinations. Most important: Space bar (next), PgUp, PgDn, Home, End.
