Hello again

I realized that instead of

Character cr
there is
Character newLineCharacter

and instead of

Transcript show: 'abc'; cr.

there is

Transcript show: 'abc'; newLine.

Here my question: What do the paragraph signs with the boxes around
them mean? (see screen shot)

>> This

>> change set that automatically captures all changes done to the Cuis Core
>> image. Changes to Packages go to separate ChangeSets.

>>        = Sorts by last definition of selector (Methods recently saved go

>>        = Sorts appropriately all selectors matching entered prefix (no

>>        = Restricts suggestions if receiver is Global, a Constant or a
>> pseudo-variable.
>>        = Doesn't have an "expanded mode". Always shows relevant
>> suggestions.
>>        = Not restricted to a set of previously selected packages. All the
>> methods in the system are accounted for.
>>        = Very fast, thanks to an optimized Trie implementation.
>>        = Compact code. Relies on services by Trie (for storing and
>> querying selectors) and Shout (for parsing incomplete methods).
>>        = Helps make Shout faster, by providing super fast queries of
>> selector prefixes.
>>        = Can be used for other applications besides Smalltalk code.
>> Currently used for an English glossary for StyledTextEditor.
>>    - Trie. Cuis 4.- includes a very optimized implementation of a Trie.
>> Tries are dictionaries where keys are Strings. Lookups are extremely
>> fast.
>> Search for entries matching a prefix are extremely fast (O(1) regardless
>> of
>> the size of the collection). Addition and removals are quite fast too.
>> Used
>> for UCompletion, holding 11,000 selectors. Also used for an English spell
>> checker (in the StyledTextEditor project) holding 166,000 words. In both
>> cases use of memory is quite reasonable (3 and 5.4 bytes per character in
>> average) and query speed is extremely fast.
>>    - Multiple level undo / redo in all text and code editors.
>>    - ClickNHalf+Drag to select words. TripleClick or
>> DoubleClickNHalf+Drag
>> to select paragraphs. Like most modern text editors and wordprocessors
>> do.
>>    - Multiple text selection (with control+mouse). Like most modern text

>>    - Lf. The newline character is no longer Character cr (ASCII code 13),
>> but Character lf (ASCII code 10). This is the standard in Mac and Unix

>> image has been converted.
>>    - cmd-w closes window below mouse pointer. cmd-< y cmd-> cycle through
>> windows.
>>    - New "PostIt" like HoverHelp morphs.
>>    - Simplification / Redesign: Scrolling in Morphic (TransformMorph
>> gone,
>> etc).
>>    - Deep cleanup in Paragraph and paragraph display services in Canvas
>> and DisplayScanner (now MorphicScanner).
>>    - MouseClickState refactor, to ease new gestures (ClickNHalf+Drag,
>> DoubleClickNHalf+Drag, TripleClick).
>>    - Killed AbstractEvent hierarchy. Unified event subscribing,
>> triggering
>> and handling everywhere in Cuis.
>>    - More TextMorph cleanup.
>>    - Numeric enhancements done by nice and jmv, both on Squeak and Cuis.
>>    - Many minor enhancements, cleanups and bugfixes.
>>    - Updates to Squeak: Numerics, Network, and many others.
>> I hope you enjoy this release of Cuis as much as Bernhard and I enjoyed

>> welcome!
>> Cheers,
