Feature - keyboard short cut for Best move arrow

Please can there be a key board short cut for best move arrow On/Off.

This would add a lot to analysis where you want to turn the arrow on/off.

I know there is one already for Local analysis (L) on/off but this does not disable the arrow if a server analysis has been conducted. The L button is very useful but it does not always disable the arrow and a short cut would be useful and easy. Thanks.

But you can use (Z).

Thank you that's very helpful. I hadn't seen that.
