I have looked at some of the answers given here and it does not seem to fit my situation.
The suggestion of using the NLA editor only repeats the animation as if it was a gif. In the attached clip I set the repeat to 2. I want the character to continue walking.
The other suggestion was to insert "Cyclic F-modifier" using Shift + E. I tried that and no popup appeared.
The online video by Olaf which uses the node editor does not make it clear how to simply movement continues.
Any suggestion will be followed up on.
