+Command in ``.edwin`` to set Super-TAB to autocomplete scheme variables::

 Scope
 --------------
-
 ``set!`` looks up a symbol name and permanently changes the first value it comes
 across. ``let`` (and ``letrec``) create a new symbol with the given value.
 But wait, you need a ``lambda`` block to make everything work?

+Environment/Interpreter Commands
+-----------------------------------
+``(disk-save filename)`` will save a binary microcode image; an existing 
+image can be specified with the ``--band`` option at runtime or with
+``(disk-restore filename)`` from within the interpreter. Bands are also called
+worlds.

+Typical .vimrc
+------------------
+Here's what a typical ``.vimrc`` looks like for me::
+
+    if has('syntax') && (&t_Co > 2)
+        syntax on
+    endif
+
+    set history=50
+    set wildmode=list:longest,full
+    set showmode
+    set showcmd
+    set smartcase
+    set shiftwidth=4
+    set tabstop=4
+    set shiftround
+    set expandtab
+    set autoindent

+    autocmd BufRead *.py set smartindent cinwords=if,elif,else,for,while,try,except, finally,def,class

+Commands
+-------------
+I search and replace globally a lot::
+
+    :%s/before/after/g
+
+Tricks
+-------------
+I often want to pull a particular gnarly line or two from another file; here's
+the command I use to grab three lines of context around 'phrase'::
+
+    :r!grep -A 3 'phrase' ../otherfile.txt
