LShift + RShift = Ctrl + Shift?

Help and Getting Started
1

Is the following possible to do in Chrysalis (gui)?

LShift = LShift
RShift = RShift
LShift + RShift = Ctrl + Shift

I would like this setup so that I don’t have to swap which thumbs are hitting Ctrl and Shift depending on which key I am typing for Ctrl+Shift+key.

No, it’s not possible to do this in Chrysalis.

I have something that works independently SpaceCadet:

int shifts_ = 0;
static void ctrlShift(uint8_t keyState, Key key) {

  if (keyToggledOn(keyState))
    shifts_ += 1;

  if (keyToggledOn(keyState) || keyIsPressed(keyState))
    kaleidoscope::hid::pressKey((shifts_ >= 2) ? Key_LeftControl : key,
                                keyToggledOn(keyState));

  if (keyToggledOff(keyState)) {
    shifts_ -= 1;
    kaleidoscope::hid::releaseKey(Key_LeftControl);
  }
}

With the following in macroAction:

  case MACRO_CTRL_LSHIFT:
   ctrlShift(keyState, Key_LeftShift);
   break;
  case MACRO_CTRL_RSHIFT:
   ctrlShift(keyState, Key_RightShift);
   break;

But if I attempt to use SpaceCadet with it, the “tap” key does not appear.

Would you have an idea of how to make the two things work together?

For reference, I got it working with SpaceCadet with the following:

/** ctrlShift presses Ctrl + Shift instead of LShift + RShift
 */

static int shifts_ = 0;
static void ctrlShift(uint8_t keyState, Key shift) {
  Key ctrl = Key_LeftControl;
  ctrl.flags |= SHIFT_HELD;

  if (keyToggledOn(keyState) || keyToggledOff(keyState))
    shifts_ += (keyToggledOn(keyState)) ? 1 : -1;

  handleKeyswitchEvent((shifts_ >= 2) ? ctrl : shift, UnknownKeyswitchLocation,
                       keyState);
  kaleidoscope::hid::sendKeyboardReport();
}
