Or footnotes may have
[Back to Ch 11]
Do you mean a < or an actual arrow symbol? Actual symbols need the font included and may not work on a Kindle if Publisher Font isn't selected by the user. Also older Kindles only have the fonts already on the ereader, you can't embed.
A < would appear, but it's to small to tap on. You need a word or phrase for links so I never put just
[1] but
a few words [1] as the source link to the footnote.
If the same footnote is used more than once then it's repeated with the appropriate
back link because most ereaders have no back button or function, only links.
Note a few readers don't even have links, so footnotes at chapter end rather than book end (Really Endnotes in textbook). Also if a note* is short?
[* just put it after paragraph like this]
