Is it possible to read a pressed Key in a lua Script?

[Airbuspilot]

Please allow me to ask another Question regarding lua Scripting.

In my Script i want to determine, which Key on the Keyboard is pressed.
Let's say for the Keyboard Letter S. I want to do the Following.
If Key S is pressed then
     Do something
else
     If Key S is released then
            Do something else
     end
end

I know about the Key Assignments in the FSUIPC Menu. But i need to do some individual Things when a Key is pressed or released.
Is it possible, to handle the Keypresses in a lua Script? I know, that i can simulate Keypresses with the ipc.keypress Command. But i need to read,
which Key is pressed. Is there a similar Command available to do this Task?

Thanks in Advance for your Help.

You don't do things like that really...
There are two choices:
   - capture the key press/release event using event.key. The lua script needs to be running to do this - such scripts are usually auto-started,
   - have two lua scripts, and assign one to be called/ran on the key press, and the other to be ran on the key release

Using events is the preferred method and will be quicker than having two separate scripts,
