No command held Cmd/Ctrl+Alt+Shift+. and Cmd/Ctrl+Alt+Shift+,, so the
chords reached Increase and Decrease Font Size (Cmd/Ctrl+Shift+. and ,)
and changed the size by one Size/Leading increment.
Two commands, type.size.increaseByFive and type.size.decreaseByFive,
now hold the chords. They step the font size of the selected type, or
of the text the Type tool has selected, by five times the Size/Leading
increment (Preferences › Type). Agents reach them with press_key too.
Their labels have rows in every complete catalog.
