  a	Select all
  b	Browse it (selection is a class name or cursor is over a class-list or message-list)
  c	Copy selection
  d	Do it (selection is a valid expression)
  e	Exchange selection with prior selection
  f	Find text with a dialog
  g	Find the current selection again
  j	Repeat the last selection replacement
  i	Inspect it
  k	Set font
  l	Cancel text edit

Also note that Senders/Implementors of it will find the outermost keyword selector in a large selection, as when you have selected a bracketed expression or an entire line.  Finally note that the same cmd-m and cmd-n (and cmd-v for versions) work in the message pane of most browsers.
  Upper-case command keys

  	or Shift-Alt on other platforms; sometimes Ctrl works too)

  Note all these keys can be used together with Shift to define or enlarge the selection. You cannot however shrink that selection again, as in some other systems.
  Other Cmd-key combinations (not available on all platforms)
  Return		Insert return followed by as many tabs as the previous line
  			(with a further adjustment for additional brackets in that line)
  Space		Select the current word as with double clicking
  Enclose the selection in a kind of bracket.  Each is a toggle.
  	(not available on all platforms)
  Ctrl-(	Toggle enclosure within parentheses
  Cmd-[	Toggle enclosure within brackets
  Crtl-{	Toggle enclosure within curly braces
  Ctrl-''	Toggle enclosure within double-quotes
  Cmd-''	Toggle enclosure within single-quotes
  Note also that you can double-click just inside any of the above delimiters, or at the beginning or end of a line, to select the text enclosed.
  Text Emphasis
  	(not available on all platforms)
  Cmd-1	type the first method argument
  Cmd-2	type the second method argument
  Cmd-3	type the third method argument
  Cmd-4	type the fourth method argument
  Cmd-5	for future use
  Cmd-6	color, action-on-click, link to class comment, link to method, url

  Cmd-9	negative kern (letters 1 pixel closer)
  Cmd-0	make plain (removes all emphasis and kerning)
  Cmd--	underlined
  Cmd-=	struck out
  Docking Bar
  Ctrl-<n> opens the n-th (where n is between 0 and 7) menu if such exists, otherwise it moves the keyboard focus to the Search Bar. Currently this means:

  'Working with the ecosystem of objects in a Smalltalk image.
  The basic tool for this is called an Inspector. Whenever you have an expression, like "3 + 4", you press cmd-i to "inspect it", which opens an inspector on the result. This works in any text area. Try for example inspecting "self" in a class browser, and you will inspect the underlying class object (which the browser shows a high-level view of).
  In the Inspector you see the objects referenced by this object (via instance variables or indexed fields) in the left panel. Select any of them and choose "inspect" from the context menu (or press cmd-i again). This way you can inspect all the objects in the system.
  A more modern tool than the Inspector (which was around 40 years ago already) is the Object Explorer. It presents you a tree view of an object and its "children", which again are the instance variables and indexed fields of the object. Open it with cmd-shift-i (or "explore" in the context menu).
  You can also do the reverse. If you choose "objects pointing to this value" you get an inspector showing all the objects that directly point to this object. Similarly there is a "reverse explorer", which you can open by selecting "explore pointers".
  There are two roots to all the objects in the system:
          Smalltalk specialObjectsArray
  which basically holds everything the Virtual Machine needs to know about, and in turn almost every object in the whole image, and
  which is the current execution context, holding onto temporary objects. When a garbage collection is performed, any object not reachable form either of these two roots is removed from memory.
  An "interesting" global object to explore is
          Project current
  which holds your current workspace, in particular
          Project current world
  , the root of all morphs in the world. And of course
  itself is the dictionary that holds all global objects, including all classes (unless they are defined in a non-global environment).
  There is also a low-level way to enumerate all objects in memory. "self someObject" will return the very first object in memory (which happens to be the nil object), and "anObject nextObject" will return the next one:
          | object count |
          count := 0.
          object := self someObject.
          [0 == object]
                  whileFalse: [count := count + 1.
                          object := object nextObject].
  Interestingly, this also finds objects that are due to be garbage-collected. For example, if you accidentally closed a text window, there is a good chance its contents will still be in memory, and can be retrieved using an expression like
          ByteString allInstances last: 10
  This makes use of the someInstance/nextInstance methods, which are similar to someObject/nextObject, but restricted to instances of one class only.
