As far as I know, you don't. It's often suggested that users try Quick Apply instead...
I think the OP wants to CREATE a KBSC. Not gonna happen with that
Isn't that what I said? Along with the suggested alternate method for reducing the amount of time it takes to choose a style when you have no shortcuts.
Um, maybe. Maybe I read it wrong because of the reference to Quick Apply
which won't do anything to create them.
If I was confused, I figure maybe the OP was, too. Or, maybe I'm the
only one who's confused.
Sooooooo... there's no current quick solution for this problem at the moment? Seems weird that the Fn key wouldn't do the trick.
I recall an iPhone app that lets you use said iPhone as a number pad.
You can make a script that applies a style, and then assign any keyboard shortcut you want to that script.
I did that for a while, but eventually just started using Quick Apply. I started naming my styles in such a way as to keep ID functions out of the Quick Apply list - starting style names with varying numbers of apostrophes or right square brackets or whatever keys are handy and unused and right next to the Enter key. It wound up being rather faster than the numpad shortcuts for documents with large numbers of styles, after a few long nights of slightly frustrating re-education.
The script for applying a character style is simple. Copy this script into Script Editor and replace YourStyleName with the character style's name (keep it inside the quotes), save it to your Scripts folder and assign a key command. The Scripts folder can have sub directories, so you could make a styles folder.
tell application "Adobe InDesign CS6"
set cs to "ExtraBold"
set applied character style of selection to character style cs of active document
