Hi jbk,
Click the
icon/button in the edit window here (with Edge browser).
Does
show up in your preview screen. I have to type : then ) to get my Smiley face to appear in my posts.
If it doesn't appear when you click the
icon/button then you have same problem as I with Edge.
BTW, when you hold the mouse pointer over the icon or tag button, it should popup an all too brief idea of what it is, that is working for me with Edge here at this site but the event of clicking the button is not.
Maybe you know but in case you don't or in case someone else doesn't know:
The # symbol/icon is for inserting your code in a code window that gives it a scroll bar. Very neat looking specially if you have a longish amount of code to post. You can copy/paste the code, then select all of it and the click the # sign, if the button is working (which it is not for me with Edge). I have to type the word code and then put square brackets on either side and then type /code with brackets again on either side. All that typing... Yikes!
