Markup language
Markup language is entered directly into the Formula Editor. For example, typing the markup
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 6 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 the Math Guide.

Greek characters
Using markup language
Greek characters are commonly used in formulas, but Greek characters cannot be entered into a
formula using the Elements window 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, in the Math Guide 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.
• For an italic Greek character, type a percentage % sign followed by the i character, then the
English name of the Greek character in lower or UPPER case. For example, typing
%iTHETA creates the italic Greek character Θ.
Symbols dialog
Greek characters can also be entered into a formula using the Symbols dialog.
1) Make sure the cursor is in the correct position in the Formula Editor.
2) Go to Tools > Symbols on the menu bar or click on the Symbols icon on the Tools toolbar
to open the Symbols dialog (Figure 275).
3) Select Greek from the Symbol set drop-down list. For italic characters, select iGreek from
the drop-down list.
4) Select the Greek character from the symbol list, then click Insert. When selected, the name
of a Greek character is shown below the symbol list.
5) Click Close when you have finished entering Greek characters into the formula.
