Modifier Keys on Stream Deck (Shift, Option, Command, Control)

Please create simple modifier keys for the Stream Deck with one click.

Current issues:

  • Requires a complex macro to simulate modifier keys on the Stream Deck.
  • Works partially: only one Modifier+Action (mouse or button) at a time. Need combinations like Shift+Option+...
  • Command key doesn't work. Bug described here: Stream Deck ⌘Command modifier key not working.

Current solutions:

  • SuperMacro Stream Deck plugin (Windows only)
  • BetterTouchTool (the only option for Mac, but without an update it works partially).
  • Keyboard Maestro doesn't work, and Karabiner can't be attached to Stream Deck.
