Footnotes for PaperWhite1

[chobile]

Hi, not sure if this is the right place... (considered putting it in conversion). sorry if it isn't.

I read a lot of web novels/light novels, which have a lot of translation footnotes/endnotes.

For a relative newbie like myself, what's the easiest way to make all the different forms of footnotes do a popup, instead of sending me to the location (chapter end, book end, etc.)

I noticed there's a
"<sup class="calibre7">[#]</sup>"
for popups when I use Edit on a book.

Is there an easy/simple way for me to have all the footnotes changed to popups automatically?

I own a Kindle Paperwhite (1st Gen,PW1), btw. Thanks.

Something like

is too technical for a dummy like me, unless someone gives me step by step instructions?
