Case Sensitive Forms
case
When the ‘change to caps’ function is applied from within an application (not when text is typed in caps) appropriate case-sensitive forms are automatically applied. Regular brackets, parenthesis, dashes and hyphens are replaced with their capital forms.
Compact prepositions and articles
calt
Replaces default glyphs with alternate forms which provide better joining. Contextual alternates are active by default in Adobe InDesign.
Discretionary Ligatures
dlig
Besides standard ligatures (fi fl ffi ffl fk, etc), Fedra Sans Display 1 contains a collection of over 800 discretionary ligatures. These ligatures are not active by default in Adobe InDesign.
Standard Ligatures
liga
Standard ligatures are those which are designed to improve the readability of certain letter pairs. For example, when this feature is activated, typing ‘f’ and ‘i’ will automatically produce the ‘fi’ ligature. Using ligatures does not affect the spelling and hyphenation of your text in any way.
Arbitrary Fractions
frac
Typotheque OpenType fonts already include a number of pre-designed diagonal fractions. The fraction feature allows you to create other fractions quickly and easily.
Superiors
sups
Replaces all styles of figures (old style, tabular, lining) and letters with their superior alternates, which can be used for footnotes, formulas, etc. Superior characters are more legible than mathematically scaled characters, have a similar stroke weight, are spaced more generously, and better complement the rest of the text.
Inferiors
sinf
Replaces all styles of figures (old style, tabular, lining) and letters with their inferior alternates, used primarily for mathematical or chemical notation. Inferior characters are more legible than mathematically scaled characters, have a similar stroke weight, are spaced more generously, and better complement the rest of the text
