Terminal, how to quit --More-- list

You can type in the Q key. ...

This doesn't directly answer your question (@saiarco895 did that), but I hate the default behavior of tab-completion in bash for the same reason. Assuming you're using Bash, you can change the behavior of the readline library it uses by editing the ~/.inputrc file. I put the following in it:

set menu-complete-display-prefix On
"\CTAB": possible-completions
TAB: menu-complete
"\x1b[Z": menu-complete-backward

which allows me to cycle through completion options without printing them out using tab and shift-tab. If I need to see a print-out of all options, I use alt-shift-?
