I tried the Blender keymap for 6 months and never really liked it, So I use a modified version of the
The industry keymap is definitely unfinished, still needs a lot of work, not sure if anyone is working on it?
I was able to move some hotkeys from the Blender map by switching to the Blender keymap, copying the command I wanted and then switching back to my keymap and creating a new hotkey and pasting in the command.
It works but its a really painful workflow. The keymap editor in Blender is really powerful but also really really confusing.
There are people out there that have created keymaps that mimic other software, I tried one that was based on Softimage, You might be able to find one that is close to what you want.
