How Do You Make A Comment On Facebook?

[dance2trance]

Been on facebook for years but no idea at all . I write in comments box and press share and it says you have not finished? No instructions anywhere.

Press ‘the right pointed arrow ’ on your key pad or even just enter

if you are making your own post, you need to press post not share.
If you are commenting on someone elses post, you just need to press return

Thank you. Both worked!
