The "Temporary value" setting applies only to the current MATLAB session and is not saved. It will be cleared when MATLAB is closed i.e. the current session is ended. In contrast, the "Personal value" setting persists across MATLAB sessions for a single user. When modified, its value is saved to the settings folder.
Hence, if you wish to change the Editor font temporarily (only for the current session), you would modify the "Temporary value" setting, and if you wish to change the font permanently, you would modify the "Personal value" or the "Installation value" setting.
Kindly refer to the following documentation page for more information on these settings: https://www.mathworks.com/help/matlab/matlab_external/access-and-modify-settings.html#mw_03a88f81-762c-4a01-8602-80956565ae6d
Hope this helps!
