Guidelines

All entries explaining commands or functions should contain subsections:

1. A description of the command. Inside the description, the group where the command or function belongs (ie, "Action Commands") should be described and linked to.
2. An examples use of the command. Examples of the command should include both screenshots of the node view of the code example, and the correct code view syntax as well.
3. If possible, external uses of the command. Suggestions for this would be forum posts.

Where to use links

Links should be made to any concept or idea (ie, loops) that has a page, and any concept or idea that does not already exist as a page should have a page created.
