When we are at it... how do shortcuts in Pharo 2 currently work?
Ouch. I can describe what I know about key event processing, and maybe
you will understand what's happening. It will be a good exercise for me
to see if I got that stuff right.
From first to process to last to process, once the key event is
generated and given to the Morph which has the focus:
1 - The morph keymapping dispatch.
This one is multilevel in nature. Here, so it goes (simplified, I'm
not listing where platform differences are taken in account). The key
event is matched against shortcuts defined in keymaps (and a partial
match is possible if it is a multi-key shortcut).
1.1 - Direct keymapping : shortcuts added by on: do: to the KMDispatcher
of the Morph instance.
1.2 - Named keymaps. Keymaps defined elsewhere and attached to that
morph keymap dispatcher.
1.3 - Global named keymaps. Keymaps associated with the morph Class or
one of it's superclass (i.e. a Morph class global keymap will apply to
all morphs).
1.4 - If no match, go to 1.1 with the owner of the morph and repeat. Do
that until you reach the World (Pharo top-level window). There, if
keymapping hasn't matched, go to 2.
2 - The morph keyStroke: handling. Normal keys, navigation keys,
hardcoded shortcuts (TextMorph for example).
-- In some cases (some! No, often :(!) keystrokes are sent to other
objects or Morphs: navigation, shortcuts, etc...
3 - The morph eventHandler : here a model can trap any key event or
shortcut.
If a match happen in any of those, the key event is usually said to be
processed and we go out of the processing loop (no more matches)
So, for a given shortcut being processed, it may be hard to find where
it has been caught. Only the Keymapping dispatch has a debugging feature
(with KMLog).
In Pharo 1.4, in the class browser, I used to hit Ctrl-F to open "Find
Class", but it has no effect in Pharo 2.
This one is easier. In Nautilus, there is a shortcut browser which lists
all the defined shortcuts. I believe that the find class is a multi-key
shortcut.

Hi all. I'm extremely new to Smalltalk, but I was wondering if there was
a way to make Pharo have vi-keys (or even better, vim-keys)?
Thanks!

It's underway. The infrastructure is moving to a better (unified) way of
specifying and handling shortcuts, and then vi and vim-keys and emacs and
others should become available.
Bad point: I should help with that effort, but given my deadlines for the
end of the year, not sure I'll be of much help :(.
