In every other operating system that I’ve used, these keys move your cursor to the beginning (home) or end (end) of your current line. Thankfully, Dreamweaver on the mac behaves this way, but everything else behaves oddly (usually moving you to the beginning or end of the entire document, and sometimes moving just the focus, while leaving the cursor in place).

To fix your “home” and “end” keys (as well as “page up” and “page down”), just download and run KeyFixer. If you already have a DefaultKeyBinding.dict file, the script will exit without making any changes.
