I don’t think the behavior is a bug. It is, as so many engineers will say, simply an “undocumented, and non-supported feature.”

However, I know that as a scripter you are very sensitive to those areas where InDesign does something that may or may not be supported in a script. As you mentioned in the ID User forum, inserting a snippet as an inline object could cause a crash when part of a script, although it doesn’t do so when part of an ordinary File > Place action.

I often think of your scripts as the canaries in the cave for bugs in InDesign. If something is in the least bit buggy, trying to do it in a script will cause a crash in InDesign.

However, often times the same behavior is OK for us normal folks using the program manually.

Meanwhile, regarding using tracking instead of kerning, I originally felt that using tracking, instead of kerning, wouldn’t work if you also wanted a tracking amount as part of the paragraph style. (Anne-Marie mentioned this to me in a private e-mail.)

However, after some testing, I am starting to think that tracking is just fine.

So, despite the trick being very clever, I think it may not be as necessary as I originally thought.

Now I think about it, it’s not entirely true that the dialog ignores the setting (it does of course include it in the summary). You can reset it along with all the other settings by using Reset to Base.

I first discovered this back in CS days (I think) when I was first working on my Text Style Reporting script. I recall reporting it and getting an acknowledgment back that this was indeed buggy behavior.

The thing is that kerning applied this way overrides the kerning either built-into the font or calculated by the Optical algorithm while tracking is incremental. If you limit yourself to using such a style only for certain characters, then I suppose it doesn’t matter.

I think it’s cool. Yes, tracking would give you a similar effect. But sometimes knowing how to trick InDesign is key to getting the job done!

Why can’t you use tracking to achieve (almost) the same ends? Granted, not using tracking opens the door to later applying tracking as a local override.

Tracking is supposed to be applied to a run of text, but if you define tracking as part of a character style and then apply that character style to a single character, the insertion point after the character is, in effect, kerned by the amount of tracking called for.
