Hi guys,

In my tagging process i usually use mixed in key to analyse the tempo and the keys.  
And it's been write in the comments section.  
I got 2 questions about it.

1. I would like to have only one key Example : 9A/9B to 9A

\*\*There is any Action expression which i can remove everything after "/"  
**Or keep only some value I write before.( in the action group section)**

1. **Also any action to copy the same comment section to key section?**

Thank you for you help.

I'm actually remove it manually.

Try an action of the type "Replace with regular expression"  
Search string: `/.*`  
Replace string:  
(leave empty)
