Problem simulating Shift+Insert, Shift+Delete keyboard combinations in windows

[vosel]

There is an issue of simulating some keyboard combinations in windows.
The combinations of the form shift+{smth}, where {smth} is 'ins', 'del', 'home', 'end', 'pgup', 'pgdn', or arrow keys are not simulated properly. The 'shift' keypress is not simulated in this situation.

It seems to me, that the similar problem is described in the following blogpost:

Here is a snippet of the simulation code I am using:

ROBOT_NS::KeyList sequence;
auto result = ROBOT_NS::Keyboard::Compile("+{INSERT}", sequence);
for (auto const & key_event : sequence) {
	if (key_event.first) {
		keyboard.Press(key_event.second);
	} else {
		keyboard.Release(key_event.second);
	}
}

This code simulates just an 'insert' keypress instead of shift+insert.
