To resolve issues starting MATLAB on Mac OS X 10.10 (Yosemite) visit: http://www.mathworks.com/matlabcentral/answers/159016
how can i save my Matlab shortcuts for use with another Matlab.
R2012a and earlier instructions: Type prefdir on the command line. Go to the folder it gives. Then copy the file shortcuts.xml from the prefsdir of the source computer to the prefsdir folder of the target computer.
[EDIT - UPDATE FOR COPYING EARLIER SHORTCUTS TO VERSION R2012b]
Apparently the new shortcuts XML file MUST be called shortcuts_2.xml.
