@raatech91 You haven't really shown what you have tried, or even really need (in detail).
I have tested some of the keyboard nodes, and two wouldn't even install, but the one from node-red-node-pi-gpio sorta worked... at least the Mouse node did, the Keyboard node just repeatedly flipped from connected to not connected. (for that node, the USB Mouse & Keyboard must be connected to the RPi)
Meanwhile... this is a (poorly hacked) add-on to an excellent example from @Steve-Mcl, that he had provided here. It works on the keyboard that is used with whatever runs the dashboard browser.
It might give you something to work with.
