How do I save custom toolbars - to use them on all documents - in LibreOffice

how do I save custom toolbars in LibreOffice ?
so i can use them on all documents

When you create a custom toolbar, you can set the scope for it. Choose one of the two options:

  1. for the actual document
  2. for the application

If you want to assign some custom (macro) functions to the custom toolbar, then the macros

  1. can be located in the actual documents or in the MyMacros (for a “document-scope-only” type Toolbar)
  2. must be located in the MyMacros (for an “application-scope” type Toolbar)

Of course you must use the 2. version if you want to use them on all documents (of a specific application). But you must repeat the setting for the other applications, if you want to create a “general” toolbar for all of the applications.
