[bbodenmiller]

Please add support for deleting items using delete key on keyboard when using windows

I personally find it a good idea too.

I have no idea why this works on Linux but not in Windows.

If anyone want to check at which keycode is recognized windows delete key, then it is enough to put between println!(button_number)

czkawka/czkawka_gui/src/initialize_gui.rs

Lines 86 to 88 in 2cc4ae3

	if let Some(button_number) = e.get_keycode() {
	// Handle delete button
	if button_number == 119 {

Since I don't use Windows, checking what exactly button is used in Windows would be helpful
