Reply To: GREP question

(a) The proper OR code is the vertical line or “pipe”:

a|e|o|i|u

— this works for entire words:

and|or|not|nor

(b) For proper searching for a set of disjunct characters, you don't need to individually OR them, you can put them into an OR set; each single character in it will match:

[aeoiu]

(c) To search for a consecutive set of characters, you don't have to list them all. Rather than

[0123456789]

you can use this notation:

[0-9]

This notation is for characters, not for numbers, so search for

[10-20]

will search for the individual characters '1', '0 to 2', '0' and not for anyrthing from 'ten to twenty' :)

(d) .. The above notation is useful, but searching for just digits is so common that they decided to assign a shortcut code to it:

d

in itself will match any single digit.

So that's how you would do it with GREP. … Thing is, under normal circumstances you don't even need this. If you are using a font that has lowercase “oldstyle” or “medieval” digits as default, and the font comes with a separate style of “lining” digits, all you have to do is change the default in your paragraph style setup — it's in the Opentype Features panel, under “Figure Style”.

If you are using a font that does not come with Opentype enabled digit styles, it will not work. But then GREP will not work either, 'cause there is nothing to change these digits to.
