We are going to make the 'Scope.java' source code and start out with an empty file called 'Scope.java' and
enter the first line "class Scope":
Now we need a curly brace "{" to open the definition of the class. Just press '{' and see what happens:
After the '{' brace, the editor knows how to indent and that's just what it does. Time to type in the
definition of the global variable. Enter 'static double pi = 3.14':
When the editor finds a keyword, it makes it red. Numbers are yellow. Unrecognized tokens (variables,
procedures and misspelled keywords) remain white. Time to add the 'main' routine body:
Now add another '{' (no need to press 'Enter'). The editor jumps to the next line and to the next indent:
Fill up the main procedure body...
Nothing special so far. Now close the main routine with the '}' token. Just press it once and see what happens:
The editor unindents the line and tracks back to the latest '{' token (and rests the cursor there for a
second) so you can see that this '}' matches that '{'. Unindenting is automatic.
Hit '}' once more and the editor adds a new line, unindents the right amount, rests on the matching '{' for a second and then goes back to the new editing position.
Jed does this with any kind of brace, round, curly or angular. It always tracks back to the one matching yours. Even in nested braces. It comes in very handy.
