7.2.7 Adding an Additional ‘kern’ Feature Lookup
In the Features section of the Font Info window, you can add
a feature called ‘kern’. Whatever you enter here will be added
as a separate lookup called ‘kernCustom’ at the end of the
kern feature in the features file. Since it is own font-wide
feature code, this additional kerning is not interpolated, but
simply added to existing, interpolated kerning pairs. This is a
good place for contextual kerning, which sometimes is needed
for punctuation or situations where negative kerning would
otherwise eat up the wordspace, e.g.:
pos f ' 60 space [T V W];
pos L' -100 quoteright' -50 A;
In the first example, the f-space pair receives an extra 60 units
only before T, V, W. In the second line, the combination L’A is
treated as follows: the quoteright is pushed into the L by 100
units, the A is also moved to the left, but only by 50 units.
This only happens in this exact constellation. Thus, the second
line does not aect the combinations L’O or l’A.
7.3 SAMPLE TEXTS
The predefined sample texts cover the most important
combinations in Latin fonts. Select Edit > Select Sample Text…
(Cmd-Opt-F) and choose a line. Use the Arrow keys to move
the cursor and the Enter key to close the dialog. You can define
your own texts in the application preferences.
7.3.1 Placeholders
If you want to space a lot of letters, you can use dynamic

next glyph by typing the current glyph. This can come in handy when you step through

your glyphs and want to see how each of them looks in
dierent situations or as a double letter. In an Edit tab, switch
to the Text tool and choose Edit > Add Placeholder (Cmd-Opt-
Shift-P) to insert a placeholder.
