-have both the forums and the emojis link as separate windows (you can right-click his link to give you that option).
-then set it up so you have both windows side-by-side
some computers, if you key the desktop window menu button (on the bottom left ) and press left or right arrows, it will lace a window to one side fro you. that’s Key windows menu + left/right arrow. You must hold down on the menu key on your keyboard and then press either arrow
Once both screens are splits, just have your messages open and drag the desired emoji into your post
unfortunately with this setup o the new forums, you can’t have it immediately following any words. It must be on its own line to activate
You can’t type any letters after it on the same line as the link, but you you hit the enter key after the emoji link, it should activate
Hope this helps
