Albert Local Bookmark Plugin

Open the URLs defined in the local plain text file.

The format of the bookmark file

# Keyword 1
http://example1.com
# Keyword 2, Keyword 3
http://example2.com
# keyword 4
http://a.example3.com
http://b.example3.com
# Keyword 5
http://a.example4.com
# Keyword 5
http://b.example4.com

That is:

• The keywords are preceded by a # and are comma-separated, and the URLs are listed below the keywords.
• Empty lines are ignored.
• The keyword and URL mappings can be 1 to 1, 1 to many, or many to 1.
• URLs with the same keyword are allowed, as the "Keyword 5" shown in the example above.
• Keywords are case-insensitive.
