Thanks Link, I had just realized a moment before receiving your reply.
I had checked the 'Do not show this information next time' box and so I had to remove my prefs files to force ArchiCAD to show me again what the shortcuts were (I couldn't remember the second set of keys i.e. '<' and '>').
BTW, isn't there an option within ArchiCAD to do just that? Isn't there a check box in some Work Environment/Preferences window that re-activates all these warning/info boxes, such as Change the background color when importing a DWG file, or Warning that certain elements have been pasted on other stories when merging files etc. _after_ the user has opted to not see them again in the future?
Or do I have to remove my prefs files, just like I did in this case?
