How to Edit Lisp Code with Emacs
This page shows you how to edit lisp code with plain emacs efficiently.
Auto Highlight Parenthesis: show-paren-mode
Turn on parenthesis highlight.
Inserting Brackets by Pairs
You should ALWAYS insert brackets by pair. I ALWAYS. Also, always delete them by pairs (I do this by selecting the whole bracket expression and delete it. Almost never do i need to only delete the brackets). Insert and delete brackets by pair will save you a lot trouble in bracket matching.
Freely Moving Cursor to Brackets
It's critical to have keys that move cursor to previous opening bracket and next closing bracket.
Navigate Lisp Code as Tree
You can also move cursor to brackets in such way as navigating a tree.
This is less useful than the freely moving to any bracket.
Select Lisp Expression by Unit
mark-sexp 【Ctrl+Alt+Space】 to select a complete parenthesized expression. Your cursor must be on the left bracket.
To select a complete sexp, type 【Ctrl+Alt+↑】
or, buy something from my keyboard store.
