Beta 4 of Google’s Toolbar adds new search functions, bookmarks, and a one-click ability to send a Web site’s URL to a blog, an e-mail account, or a cell phone.

The enhanced search function displays a list of keyword suggestions as you type your query.

Google Bookmarks allows you to access favorite sites on any computer running Beta 4.

The Send To command lets you send a page by e-mail (using Gmail), via text message, or as a link to your Blogger-hosted blog.
