In the Mac docs for IntelliJ Idea they use the keyboard icon (⌨) for some of the keyboard shortcuts. It implies one should hit all the keys, but on usb inputs you can only press six keys simultaneously (and this is the case on current Apple laptops).
Joking aside, how do you translate the following into plain English instructions?
⌥⌘⌨ *, 1
See an example in the docs here. Make sure to have your keymap set to Mac OS X (10.5+) (do this in the upper right hand corner)
