I understand that I can configure different layers where one layer contains LeftGui on a key and another contains Alt+F2. But is it possible to configure Shift+LeftGui to input Alt+F2?

It doesn’t seem sane to configure Shift for such layer change behaviour. So is this really hare-brained/impossible/not worth it?

```auto
namespace kaleidoscope {
class SLAltF2 : public kaleidoscope::Plugin {
 public:
  SLAltF2() {}

  EventHandlerResult onKeyswitchEvent(Key &mappedKey, byte row, byte col, 
                                      uint8_t keyState) {
    if (mappedKey == Key_LeftGUI && hid::wasModifierKeyPressed(Key_LeftShift)) {
      hid::releaseKey(Key_LeftShift);
      mappedKey = LALT(Key_F2);
    }
    return EventHandlerResult::OK;
  }
}
}

```

Something along these lines. The idea is that whenever a key is pressed, we check if that is the GUI key, then check is `Shift` was pressed previously, and if so, release shift, and change the current key. Otherwise leave everything as-is.

This only works when you press `Shift` first, but can be adapted to work in case `Gui` goes down first, too. Adding support for right shift is left as an exercise for the reader. 🙂

This won’t work if your intention is to use those two left-side thumb keys with the same finger on the default layout, but here’s another option that might also work for you:

You could use Qukeys to configure any of your modifier keys to be `F2` when tapped, and use your regular `alt` key normally to modify it. For example, you could replace `Key_LeftGui` with `GUI_T(F2)` in your keymap. Then holding alt and tapping cmd would result in `alt`+`F2`.

[Note: Qukeys is a lot of code. If you just want this one thing, it may be less work to implement it with the existing plugin, but @algernon’s solution has a much, much smaller footprint on the MCU, so if your sketch is already pushing the boundaries of the chip’s memory, a miniature custom plugin is the way to go.]
