Most indenting of program code is best handled by the VLISP automatic code formatting and Smart Indent features, and by customizing the formatter's options (see Formatting Code with Visual LISP). But there are some things you may want to do by yourself.
To indent selected lines of
code, press TAB or press CTRL + E, and then choose Indent Block.
VLISP inserts a TAB character at the beginning of each line you
selected. You can control the indent amount of the TAB character by
choosing Tools Window Attributes
Configure
Current and setting the Tab Width value. You can also use the following
keyboard shortcuts to adjust the indentation of text.
