Hello there!
I would like to understand the difference between

[bbp-search] – Display the search input form.
[bbp-search-form] – Display the search form template.

I tried both of the shortcodes and they gave the same result, and my english is not good enough for me to understand the difference by reading the description. So please help.

and I have the same question for

[bbp-reply-form] – Display the ‘New Reply’ form.
[bbp-single-reply id=$reply_id] – Display a single reply eg. [bbp-single-reply id=32768]

and for

[bbp-topic-form] – Display the ‘New Topic’ form where you can choose from a drop down menu the forum that this topic is to be associated with.
[bbp-topic-form forum_id=$forum_id] – Display the ‘New Topic Form’ for a specific forum ID.
[bbp-single-topic id=$topic_id] – Display a single topic. eg. [bbp-single-topic id=4096]

and for

[bbp-forum-form] – Display the ‘New Forum’ form.
[bbp-single-forum id=$forum_id] – Display a single forums topics. eg. [bbp-single-forum id=32]

thank you for your answers!
