Possible to change mappings while certain FZF buffers open?

Hey all, I really love the fzf plugin, it's totally changed the way I use vim and I love it.

I'm wondering if there's a way to make a remap for the fzf buffer for certain commands?

in my case, I want to make a keybinding, only for the `:Files` command (and derivatives) to bind `` to `/` so that space separating words will produce a proper filepath.

Currently, if I type "outer inner file name .py" - it won't find the file, but the file I wanted was `outerdirectory/innerdirectory/files/name.py`

I think mapping space to `/` should solve, this, as space is never needed in filepaths, and it's so automatic to press ( I use it in every other command so hard to train myself out of)

I did see that we can set autocommands for the `fzf` buffer type, but that will be for all fzf buffers; perhaps if there was a way to find out what was used to invoke the fzf command? I could also see the `g:fzf_actions` but that also didn't seem to be quite what I was looking for.
