[sup-talk] Best practice for customizing keymaps?

[David Adams <daveadams@gmail.com>]

Hello everyone,
I'd like to make some customizations to the default keymaps for a few
modes, and I was wondering what was the safest way to do so. On the
Hooks wiki page, the entry for startup.rb shows how to add keystrokes,
but based on trying that example out, it appears to work only for
adding new keystrokes, not overriding existing ones.

So after poking around at the code a bit, dropping this code into
startup.rb seems to work to entirely replace a keymap with my
preferences:

class Redwood::Mode
  @@keymaps[Redwood::ThreadViewMode] = Redwood::Keymap.new do |k|
    # key mappings omitted
  end
end

So my questions are: Is this unsafe in any way (other than that new
versions of sup may invalidate the specifics of keymap
implementation)? And is there a better way?

Thanks!
