Vinry_.: You type the name, then on the left side you'll see four boxes each indicating different symbols for different functions. Click the rightmost one while having that name you've just typed highlighted. You'll then see this [url=][/url]. What you need to do now is just copy and paste the link to the video after the url= . Next to the url= should be the text of whatever name it is you typed. You'll need to erase that and replace it with the link.
In your case, it'd be like this:
[url= https://youtu.be/x2wIRlxMg-E ] Machine Robo Honoo (Machine Robo OP 1 Full) [/url] (Ignore the spaces, except for the spaces that are already in the name of the video to begin with ofc)
So in a way, the better question would've been "How do I make the name have a link?" Lol
