Hi Finema,

> How to install it (v3.1) without losing my shortcut keys and command (V3) ?

The shortcut keys are stored in the moi.ini file which will be in your user directory. Version 3.1 will use that same moi.ini file so the shortcut keys setup will be the same in 3.1 as it was in 3.0

If you've added any additional plug-ins in the commands folder, you will need to copy those over from the Version 3.0 commands folder into the Version 3.1 commands folder. It's ok to just copy all files and say "no" when Finder asks you if you want to overwrite files.
