Global tags are global metadata rather than stream/track metadata

sorry but what does that do or mean and how to use it

thanks just learning

It's the same "stuff" you put on a music file. The info that tells you the title, the artist, the album, etc. This is called metadata or more commonly tags. Tags that which describe the file as a whole can be called "global". Since matroska can have many streams (video, audio tracks) you might want to add tags specific to that stream/track. These are the not-global kind.

MPC(-HC) will read some of them and display them (TITLE and COPYRIGHT at least) when you have the Information pane open. Mkvextract (or MKVCleaver) can dump them out as a file if you want to see exactly what is there.
