Yes, that’s right, the shortcut scheme has been published by @freyalupen here.
If you don’t know how to create the “csp.shortcuts” file yourself, you can either download it from my cloud or try my tutorial, which tells you how to create and import the file into Krita (which at least worked for me).
If my instructions don’t work (which was the case for at least one user), you can also install the file by copying it into Krita’s resource folder in the subfolder “shortcuts”, if the subfolder “shortcuts” doesn’t exist you have to create it yourself first. Krita’s resource folder can be accessed either with the file manager of your choice or via ‘‘Settings’’ >> ‘‘Manage Resources…’’ >> ‘‘Open Resource Folder’’ from within Krita itself (Krita will then open a file manager window directly in the resource folder).
With both methods, Krita must be restarted afterwards.

Addendum: Here, in the post after my tutorial, @freyalupen wrote down some more information about the shortcut scheme that might be of interest.
