The //Open 1Password Bookmark// action is for those who have the 1Password application installed. Select the specific bookmark to open from the //Open 1Password bookmark// pop-up. You can select (v9.0+) whether to view the bookmark, open the bookmark, or open the bookmark with a specific URL. Note that you need to enable 1Password’s advanced preference to allow third party programs to read your bookmarks (they have access to the name and URLs, but not the passwords).
