How to loop through a keyword in Workflow Manager

Question:
How do I loop through a keyword field or variable in Workflow Manager?

Answer: 
At first, please be aware of a known limitation when using loops; after one task (e.g. condition "loop condition") has ben executed 50 times without human interaction the loop detection will be triggered and the workflow will be unpublished! Here's how to avoid that (On-Premise only).

Now that you know, you can set up the "keyword loop" using the following steps: 

1. Create empty tasks, name and connect them as in the screenshot
   
2. Create the following three variables: keywordCount (Numeric), i (Numeric), lineContent (Text)
   
3. Set the loop counter to '0' and get the count of lines in the keyword field
   
4. In the condition, you check if the loop has to run again or is at its end
   
5. Inside the loop, you get the text of the line you are processing at the moment and increase the loop counter
