Coding UP STAR

When coding UP STAR while editing an article it may be written:

• In plain text, using an HTML entity for UP and a normal asterisk for STAR: “↑*”, yielding “↑*”; this raises the star unwantedly, which is not quite consistent with printed CGT texts, but not too bad.
• In MathJax, using the codes “uarr” and “ast”:
  • Do not use MathJax in the text of a link nor in a section heading or diagram title (both of which generate links in the Table of Contents).
  • It is preferable to use a literal (with an HTML entity) for UP (but not for STAR): “`` "↑"ast ``”, yielding “``"↑"ast``”.
  • Enclose in invisible brackets if part of a larger formula: “`` uarr - ast = uarr + ast = {:"↑"ast:} ``”, yielding “`` uarr - ast = uarr + ast = {:"↑"ast:} ``”.
    • If anyone discovers a simpler way to achieve this, please note it here.
  • The simpler code “`` uarr ast ``”, yields “`` color(DarkRed)(uarr ast) ``”, which unfortunately contains a confusing extra space.
