[VNC] using phone from desktop?

I would like to use my phone from my desktop computer via VNC, especially for writing stuff. I know there have been a few posts in TJC about VNC but I can’t seem to find them again.

There’s this project, which I installed once IIRC but it was not possible to use the desktop keyboard (to send keyboard events):

Did anyone manage to use the keyboard through VNC? Do you know any alternatives to lipstick2vnc?

I know there are a few projects for getting remote desktop access from the phone (but that’s not what I need):
