Here is what I am wondering processing can do:

- a sketch with a fully transparent background that shows apps behind it
- a link in size and position to a certain window
  - kinda being attached to it
  - maybe even having a pre-defined window name to attach to?

- inputs only going into the sketch when a key is held
  - clicking ignored by sketch, going into windows behind it
  - ctrl-clicking is seen in the sketch, but not the windows behind it

I have an idea for a tool and really hope I can make it work.  
If this cant work in processing, does anyone know any other Java based IDEs that could do this?

Past discussions of transparent Processing sketch frames:

- [https://forum.processing.org/two/discussion/11629/is-it-possible-to-make-a-transparent-window](https://forum.processing.org/two/discussion/11629/is-it-possible-to-make-a-transparent-window)

The routing of input to a specific app is an operating-system level controlled application consideration. If you want a hotkey to bring the Processing app into focus, you will probably need to use a macOS or Windows or Linux hotkey manager. This isn’t specified in the Processing app itself.
