Sending multiple modifier keys by pressing the butterfly key (shift & ctrl)

Help and Getting Started
1

Hi,
how can i set the butterfly key as a double modifier key (shift & ctrl)
thx

2

Use LSHIFT(Key_LeftControl) in place of Key_RightAlt in your firmware sketch. That should do the trick!

Great it works! Very handy to select by word with the arrow keys thx

And can we add the shift to function layer also to make it triple would be great

Do you mean that the key should act as Shift + Control and shift to the FUNCTION layer too? In that case, the PrefixLayer plugin could be put to good use, I believe. Unless you want another key that shifts to the layer without having Shift + Control pressed.

If the latter, then a macro could do the trick:

void macroShiftControlLayer(uint8_t keyState) {
  if (keyIsPressed(keyState)) {
    kaleidoscope::hid::pressKey(Key_LeftShift);
    kaleidoscope::hid::pressKey(Key_LeftControl);
  }
  if (keyToggledOn(keyState)) {
    Layer.on(FUNCTION);
  }
  if (keyToggledOff(keyState)) {
    Layer.off(FUNCTION);
  }
}

(Untested, mind you, but something along these lines.)

I mean like you press the 3 keys at the same time. The shift + control + fn

Thx for your quick response

hi,

i tried with the TMUX layer and added the keyhook

Key tmuxEventHandlerHook(Key key, byte row, byte col, uint8_t keyState) {
if (keyState & INJECTED)
return key;

if (keyToggledOn(keyState) && key != ShiftToLayer(TMUX) && Layer.isOn(TMUX)) {
handleKeyswitchEvent(LSHIFT(Key_LeftControl), UNKNOWN_KEYSWITCH_LOCATION, IS_PRESSED | INJECTED);
kaleidoscope::hid::sendKeyboardReport();
handleKeyswitchEvent(LSHIFT(Key_LeftControl), UNKNOWN_KEYSWITCH_LOCATION, WAS_PRESSED | INJECTED);
kaleidoscope::hid::sendKeyboardReport();
}

return key;
}

and added
Kaleidoscope.useEventHandlerHook(tmuxEventHandlerHook); in the setup function

the layer works but the hook doesnt… do anything
