\\{icon-mode-map}
Variables controlling indentation style:
icon-tab-always-indent
Non-nil means TAB in Icon mode should always reindent the current line,
regardless of where in the line point is when the TAB command is used.
icon-auto-newline
Non-nil means automatically newline before and after braces
inserted in Icon code.
icon-indent-level
Indentation of Icon statements within surrounding block.
The surrounding block's indentation is the indentation
of the line on which the open-brace appears.
icon-continued-statement-offset
Extra indentation given to a substatement, such as the
then-clause of an if or body of a while.
icon-continued-brace-offset
Extra indentation given to a brace that starts a substatement.
This is in addition to icon-continued-statement-offset.
icon-brace-offset
Extra indentation for line if it starts with an open brace.
icon-brace-imaginary-offset
An open brace following other text is treated as if it were
this far to the right of the start of its line.
Turning on Icon mode calls the value of the variable icon-mode-hook with no args,
if that value is non-nil." (interactive) (byte-code "ш !ԉՉ
