Here's the list of some labels of Template form ("Configuration -> Templates -> [Template name]"):

• In groups
• Other groups
• Other | group
• Hosts / templates
• In

These labels could be improved, there is now way a new user could understand "Other groups" and "Other | group". Besides they both have the same list of options. Also different delimiters "/" and "|" are confusing. This can not be cleared out from documentation either, not all of them are documented in https://www.zabbix.com/documentation/3.4/manual/config/templates/template
