My video card isn't quite up to the game so I can't be sure if what I am seeing is really what is happening so I hope someone else can confirm.

When using the bayonet to melee is the only way you can kill is Left Clicking with the gun properly lined up and right distance from the target?

Or is it possible to kill when in melee mode with the bayonet by using Shift key to go into Charge?
The animation shows you charging with your gun and bayonet positioned forward but it is unclear from my PC whether I have ever killed that way. So far it looks like it still requires you to left click to thrust and kill.

Can anyone confirm this?
