Opening a program in administrator with Arduino (DigiSpark/DigiSparkKeyboard)
Looking at the code, the first argument should be the key, and the second the modifiers. So DigiKeyboard.sendKeyStroke(MOD_CONTROL_LEFT + MOD_SHIFT_LEFT + KEY_ENTER); should become:

DigiKeyboard.sendKeyStroke(KEY_ENTER, MOD_CONTROL_LEFT + MOD_SHIFT_LEFT);`
