Multiple Modifiers

[Younghart]

Hello,

I'd like to send multiple modifiers, with a key and also without. Is there a way to define two or three modifiers at the same time, with a single or multiple keycode(s)?

Sorry for the late answer (I wrongly assumed Github would send me a notification for new issues/PRs).

Yes, both is possible and supported. You can press send multiple modifiers at the same time by combining them with the bitwise or operator |.

Consider the following example:

// send CTRL+SHIFT+D
mKeyboard.sendKey(mKeyboard.asciiToKeycode('D'), MODIFIER_SHIFT | MODIFIER_CTRL);

Also have a look at examples/SendMultipleKeys on how to send up to 6 keycodes at the same time (also possible with multiple modifiers).

If you want to send just a modifier without another key, you have to specify the keycode of its button instead, e.g.:

// send left GUI
mKeyboard.sendKey(0xe0);

The keycodes for just sending modifier keys are the following:

left ctrl:    0xe0
left shift:   0xe1
left alt:     0xe2
left gui:     0xe3
right ctrl:   0xe4
right shift:  0xe5
right alt:    0xe6
right gui:    0xe7

Hope I could help you!
