In semiconductors Current flows in direction of 'arrow' OK ! for forward

That is a good way of thinking about it. The diode inside the package is
still going in the same direction, it's just that you are applying reverse
voltage when you are using the zener breakdown.

And just to make it all clearer, electron flow is opposite to
conventional current flow !

Blame it on Franklin. He made an assumption about lightning that turned out
to be wrong and 250 years later we still have to deal with it.

Unless you're in the US military where it's all backwards.... or forwards...
