There exists just a few changes in the Keyboard shortcut function/command opportunities going from Premiere Elements 13, 14, 15, and 2018. The above was prepared from what was seen in my Premiere Elements 2018 Windows 7 Professional SP1 64 bit (Expert workspace/Edit Menu/Keyboard Customization/Application and Windows categories). All is being triple checked for accuracy in what is presented here. If any errors found in the above, it will be reported here immediately.

Apologizes for corrections due to Save failures during correction of Master files to 2018 information. I will continue to monitor for any further oversights.
