@הערשלה here is the screenshot for your reference:
If you are using the emoji plugins then there are a lot to be listed. You could list the basic most common images.
They also show in a drop down menu so if know the start then you can scroll to what you need so if you type
:ton then the menu opens with the option to place tongue image.
Think about me. I had no idea such a smilies existed. When I type : I get a drop down list of emoticons (good thing), but only first 3 smilies are visible. Since the reply box is fixed, even scrolling doesn't help. We need to be idiot proof. I guess emoji plug in is not installed here.
