Looks like there is still no alt-e-s shortcut available in Excel to bring up the Paste Special panel? Command-control-v still works to bring it up but it still doesn't allow you to use another shortcut to specify the type of way to paste (i.e. v for values, f for formulas) like in the Windows version. Looks like the Customize Keyboard menu item is not available here either (although I could never get alt-e-s mapped properly in previous versions either). .
im hoping this gets fixed before final. also missing are all the shortcuts to specify actions on the ribbon. for example pressing Alt H doesn't bring up the home ribbon. This means you also can't use shortcuts from windows excel that let you do key sequences (like Alt -e-s-f). Considering how hard theyre trying to bring a similar windows experience to mac this would be a huge thing to overlook since it adds alot to productivity.
