Matching Parentheses

Matching Parentheses

Visual LISP provides a parenthesis matching feature to help you find the close parenthesis
that corresponds to an open parenthesis.

To match an open parenthesis with its corresponding close parenthesis

  1. Place your cursor in front of the opening parenthesis that precedes the setq function call.
  2. Press Ctrl+Shift+]. (Double-clicking also does the trick.)

Visual LISP finds the closing parenthesis that matches the one you chose, and selects
all the code in between. Not only does this ensure you typed in the correct number
of parentheses, it also makes it easy to copy or cut the selected text. This might
have come in handy when you updated this call at the end of Lesson 4.

Why else might you want to do this? You can copy some code to the Visual LISP Console
window, paste it there, and try it out. Or maybe you have figured out how to replace
50 lines of code with three really marvelous lines of much better code. You can quickly
select the old code using the parentheses matching tool, then eliminate it with a
single keystroke. It is a lot quicker to let Visual LISP find an entire block than
for you to hunt down every last closing parenthesis.

There is a corresponding key command for matching and selecting backward. To try this,
put your cursor after a closing parenthesis, then either double-click or press Ctrl+Shift+[.
Visual LISP searches for the corresponding opening parenthesis, and selects it along
with the enclosed code.

Both commands are also available by clicking Edit Parentheses Matching from the Visual LISP menu.
