Change clip height shortcut

In the keyboard commands, it says that there are hot keys for clip height. cmd+shift+"=" to increase, and cmd+shift+"-" to decrease. But neither do anything. Anyone know how to use these or get them to work?

[Neil Sinclair] " I'm using the 'minimise' with Roles"

I use this as well...but I'm confused that it doesn't seem to affect clips in the primary or secondary storylines?

This seems like an oversight...I want to minimize everything. I rather like doing this by roles...I can work on tweaking VO levels...then minimize all VO. It's pretty slick. (unless it's in a storyline! :) haha...
