I've this org-file:
* Headline a :tag1:
Text for my Headline a
* Headline b :tag2:
Text for my Headline b
* Headline c :tag1:
Text for my Headline c
* Headline d :tag4:
Text for my Headline d
What is the command to get the following output (show only headline with tag1)?
* Headline a :tag1:
Text for my Headline a
* Headline c :tag1:
Text for my Headline c
