Inline Comment or a quicker way to comment a block?

[newjie]

I hope I can just use "//" to comment out a line or to add some comment to a line, but it seems to me {% comment %}{% endcomment %} is the only way to comment out something, which is a lot of typing. If it is true, is there any app or browser extension to make this a one-click thing?

@newjie you can now use {% # This is a comment %} 👍
