About More and Exchange
These are two operations not seen in most other environments (other than Squeak ;-), but you'll like them if you try them. More is like search-and-replace except that you don't have to plan ahead. Overtype a variable name and then, when you remember it is used elsewhere, just type cmd-M -- it will find the next occurrence and make the same replacement. You can also use cmd-SHIFT-M to make the same substitution throughout the remaining text.
Exchange is also unusual in that it depends not only on the current selection, but also the previous selection. This is a minor no-no in UI design, but you will find it to be entirely natural. For instance, select one line of text (twice-click at left margin) and then select another line, after which cmd-E will exchange those two lines. Similarly the then and else clauses of an if statement can be exchanged with this one command.
