Ctrl-L is an alternative to the clear command.

On my machine ctrl-PgUp does not move up the screen, but upward mouse 
scrolling does reveal the history again. So, here's an additional note.

If you don't want to see that history as a result of mouse scrolling, for a 
particular user's home directory, and for bash as a shell, move the 
file .bash_history to a different file name, say .old_bash_history. Then 
create a new history file. So, in the home directory:

ls -la .bash*    reveals existence and size of the current .bash_history.
MTV .bash_history .old_bash_history    renames the file.
touch .bash_history    creates a new file without the previous history.

Now ctrl-L or clear will operate as before with less history to reveal.
