Hello Meir,
If you export all registry settings in the HKEY_CURRENT_USER\SOFTWARE\EmSoft\EmEditor v3, there should be no problem. The keyboard shortcuts for macros are saved in the Accel and PIKM values in each configuration name under HKEY_CURRENT_USER\SOFTWARE\EmSoft\EmEditor v3\Config. These are binary values so you won’t be able to search in the registry editor.
Thanks,
