Thank you for asking.

If you have customized shortcuts, you can back them up by following these steps: 1. Go to the top menu, select 'Explore > Tools > Command Aliases Editor' 2. Once in the editor, navigate to "File" and select "Export". 3. Then, reset to defaults by going to "File" again and selecting "Import" 4. Now you can import the previously saved file to restore your custom shortcuts As for backing up system variables: 1. Navigate to "Tools" in the top menu 2. Select "System Variable Manager". 3. Near the top center, there should be a disk icon for saving. Click on it to save your settings. 4. On the left side, there's an option for loading. After reinstalling, load the saved settings from here. Please follow these steps to ensure your shortcuts and system variables are backed up and restored correctly after the reset.

Thank you!
