Reveal and Customize Hyphenation Break Points
As an InDesign user lamented in a recent post on a forum, there’s no keyboard shortcut (a la Ventura Publisher) or dedicated menu command (a la QuarkXPress) to see the possible hyphenation points in a word. That is, in a multisyllabic word, between which two syllables does InDesign’s dictionary prefer to hyphenate it when it must, and where are the other possible breakpoints in the word that the dictionary will consider? He’d been looking for an hour in InDesign and couldn’t figure out how to reveal this information.
Actually, the feature is only a little bit hidden in InDesign, in the Edit > Spelling > Dictionary… command. (If you do this a lot you might want to assign a custom keyboard shortcut to the command.) When you choose Dictionary…, a dialog box opens that lets you enter the word for which you’d like to check spelling or hyphenation points. (If you select a word in your document before choosing the command, the word is automatically entered in the field.)
When the word is in the field, click the Hyphenation button to reveal the breakpoints the dictionary knows about. One tilde (~) is the preferred location, two tildes indicates a less satisfactory alternate breakpoint, and three tildes indicates InDesign’s last choice.

If that’s all you want to know, you can click the Done button and be on your way. If you want to customize the breakpoints, go ahead and insert or remove tildes as you deem fit, following the rule of one tilde = preferred, more tildes = okay to break here if the preferred location doesn’t work. Adding a tilde in front of the first character and removing all the other ones from the word tells InDesign “Don’t hyphenate this word, ever.”
When you’re done customizing the hyphenation breakpoints, click the Add button to save your hyphenation exception to the dictionary. When you click the Done button, InDesign runs through your document and recomposes it with your exceptions as necessary.
I thought it was the other way around. One tilde is the preferred break point. At least according to my experience and the Help file.
Uh … yeah. I was just testing you.
Correction made … must have been in a dyslexic mood when I wrote that!
Something else worth noting, I think, is the fact that if you’re going to create a custom dictionary, you’re going to want to share it with anyone else working along with you
This is an extremely useful tip for me. I have instances of a hyphenated product name that I want to never break and ID wants to break it after the hyphen in the name. Adding the tilde before the word in the dictionary just saved me lots of tweaking.
What if my User Dictionary has no entries? Every word that I test has no hyphenation rules at all. We run on non-admin accounts. Could that be the issue?
