A couple questions about device parameters / reactions

Hi, I’m making a remote script for the Midi Fighter Twister and have a couple questions, hope someone can help:

• Is it possible to display a device parameter’s value in the Live status bar? Currently, only the parameter name appears, not the actual value. I’ve tried using reactions, but it doesn’t seem to work… maybe I’m missing something?
• Can a keyboard shortcut be triggered when a button is pressed?
• I have my control setup so that it detects the selected device name and adjusts the LED colors of each knob based on it. For example, Compressor uses one set of colors, while Delay uses another. Now, I want a side button to control the 17th parameter of the device, and when pressing it, momentarily change the LED colors of 2 knobs to Green, then revert back to the previous colors. Right now, I can change the colors when the button is pressed, but the MIDI controller then reverts to the default value (0 / Off Color) instead of going back to the ones based on the device name.

Thanks a lot
