1. C-h f local-set-key RET
2. the documentation of local-set-key tells you how to do it:
The binding goes in the current buffer's local map,
which in most cases is shared with all other buffers in the same major
mode.
Therefore you should create a buffer local map distinct from the major
mode map.
3. M-x apropos RET local map RET
4. find a command that lets you create a local keymap.
5. use local-set-key with the new buffer local map.
