Looks
Each character has a "look". You can query and change looks with the EditTool. You can also use the keypad "9" key as a shift operator to change looks. Holding down keypad-9 and 'b', for example, will set the current selection to have look 'b' (usually bold). A character can have multiple looks, and some appearances come for free from the format (see below).
Although each style defines its own look characters, here are a few from the Cedar style, which is the default. Find these and more in /PCedar2.0/EssentialStyles/Cedar.style
b - bold f - fixed-pitch font
i - italic l - larger font
p - plain font q - quaint logo font , i.e. XEROX
s - smaller font v - video reverse
x - extra large y - strikeout
z - underline
Formats
Each node has a format. You can query and change formats with the EditTool. You can also change the format of the node you are typing in by typing the name of the format and then a CTRL-keypad-4. This erases the word that named the format and sets the nodes format.
Here are some of the formats defined in /PCedar2.0/EssentialStyles/Cedar.style
body - for paragraphs with indentation center - for centered paragraphs"
code - for Cedar program statements example - for examples embedded in text
head - for section headings at any level indent - for indented paragraphs
logo - for Xerox logo note - for fine points
table - for 40sp tab stops table1 - for 30sp tab stops
pageBreak - to force a new page
Mesa Editing
There are a couple tricks to help editting Cedar programs easier.
CTRL-E does abbreviation expansion. Type a keyword and then
CTRL-E and the keyword will be expanded. Here are most of the abbreviation keywords for the cedar style. See /PCedar2.0/EssentialStyles/cedar.abbreviations for a complete list.
modules prog, monitor, defs, dir, using
procedures proc, pproc, eproc, peproc, iproc
conditionals if, else, ifelse, select, from, with
blocks begin, {, [, exits, goto
loop control do, for, in, through, until, while, repeat, exit
miscellaneous ret, rets, type, rec, footnote, file
CTRL-M will format the current selection as Cedar code. This depends on proper capatilzation of keywords (all caps), procedure names (begins with cap), and variables (lower case). The following operations on the current selection can help you achieve this:
CTRL-SHIFT-C - All caps. CTRL-C - All lower case. CTRL-C-C - Capitalize first character.
