Recommendation for Text User Inteface (5 Keys + Text Display)

Hello everybody.

I wonder if any of you could recommend me a simple library to build a menu for displaying a text menu on an OLED Display (128X64 pixels). The menu should be managed with 5 keys (UP, DOWN, LEFT, RIGHT and OK) to move over the menu and change settings.

The OLED is a SSD1306 for which I have jet an Adafruit library.

Thank you.
