Describe the feature

I could do this by just unmapping on the various buffer types, but I would like a way to disable the edit alternate hot key on pinned buffers, specifically a buftype="terminal" buffer, where I don't want normal mode Ctrl-6 (which in vim is one of the build in/standard mappings) to change the buffer.

Provide background

No response

What is the significance of this feature?

nice to have

Additional details

I have confirmed that the buffer is pinned (lua= require'stickybuf'.is_pinned())
