Markup language
Markup language is entered directly into the Formula Editor. For example, typing the markup
language 5 times 4 into the Formula Editor creates the simple formula
5×4
. If you are
experienced in using markup language, it can be the quickest way to enter a formula. Table 2
shows some examples of using markup language to enter commands. For a full list of commands
that can be used in the Formula Editor, see Appendix A Commands Reference.

Greek characters
Using markup language
Greek characters are commonly used in formulas, but Greek characters cannot be entered into a
formula using the Elements dialog, Elements Dock, or the context menu. Use the English names of
Greek characters in markup language when entering Greek characters into a formula. See
Appendix A commands Reference for a list of Greek characters that can be entered using markup
language.
• For a lowercase Greek character, type a percentage % sign, then type the character name
in lowercase using the English name. For example, typing %lambda creates the Greek
character λ.
• For an UPPERCASE Greek character, type a percentage % sign, then type the character
name in UPPERCASE using the English name. For example, typing %LAMBDA creates the
Greek character Λ.
