Yes, LCDproc supports input keys.
But it depends on the hardware to provide them 
and the LCD driver to detect them.

Sicne you talk about the parallel port,
I guess you talk about the hd44780 driver.
This driver supports keys.

LCDd, the server part of LCDproc usually rotates all the screens 
in a round-robin manner. But you can use keys to switch immediately to the 
previous or next screen.
Of course there are also keys to halt the screen rotation and to restart it.

In addition to that you can select the screeens being shown by the lcdproc 
client.

What menu structure ?
If you want shell commands to be executed, the lcdexec client is the
thing for you.
In its configuration file you define a menu structure and the associated 
commands when an entry gets selected.

Unfortunately it lacks a bit documentation.
But a quick  look at the lcdexec.conf configuration file will get you an idea 
how it works.
