When I hook an Arduino to the USB port on my laptop, the loaded sketch will run and I can monitor any serial prints in the serial monitor window.
I can also scroll up and down in the serial monitor using my laptop keyboard or mouse.
Now if I if I hook a serial LCD (e.g. 1602 or 2004) onto the same Arduino and power it from a wall-wart (i.e. it is not connected to the laptop USB port), I can replicate the serial prints and monitor the output on the LCD.
What I would like to have is the ability to scroll up/down through previously displayed output on an LCD (or other type of display) - like I am able to do with the serial monitor.
If I add a keypad to the mix, can the above-stated goal be made a reality?
FWIW I would prefer using a separate keypad and not an LCD+keypad shield.

Do you mean a 16 character x 2 line LCD display? AFAIK they have no internal scrolling logic or the ability to store data that is not visible.
If you want to be able to see earlier data you will have to save it in the Arduino and arrange for your Arduino to re-display it. Because of the small Arduino memory that may not be a practical option.

Yes you. Right click the word and select add to dictionary.
