Where can I found the shortcut in scrivener?
Sorry, what shortcut?
If you mean all of them, there isn’t a routinely maintained list available. The closest is this article:
Which is pretty up to date, but it might have a few inaccuracies. The menus are the list of shortcuts. If you are not sure where a menu command is, but know what it is called, you can use the Help menu on 10.6+ to search for menu names. This will highlight the menu item itself, and that highlight will include the shortcut. Shift-Cmd-/ will bring up that help search, by the way. It’s actually so convenient that it can even be used to trigger menu commands that otherwise do not have any keyboard access. So it’s a nice trick to know anyway.
