By default, the OS X help window automatically overlays other screens. I’ve now added to my lab imaging sequence to disable this as I use help windows from time to time but want other windows in the foreground when I command-tab to them. To make the change, write a DevMode key as boolean true into com.apple.helpviewer using the defaults command as follows:
defaults write com.apple.helpviewer DevMode -bool true
To disable:
defaults write com.apple.helpviewer DevMode -bool false
