Here is a fun trick to try in your favorite web browser. Paste the following snippet of javascript code into the address bar where you normally type a web address:

This tiny script tells your web browser window to jump to 800×600 pixels in size. A handy shortcut for web designers proofing sites. Here are a collection of resize links based on that simple javascript code:

Resize Link: 640×480
Resize Link: 800×600
Resize Link: 1024×768
Resize Link: Full Screen

You can save these links as Bookmarklets — small javascripts saved as normal bookmarks — to easily resize your browser windows on the fly.

In the rest of this tip we’ll walk you through adding Bookmarklets in Safari.

Here is a technique I use every week while proofreading final drafts of this tips newsletter. When you need to proof your final documents or important email, have your computer read the text out loud to you and listen for mistakes. You’ll catch errors you might otherwise miss.

In many OS X applications, you can highlight your text and choose [Application] > Services > Speech > Start Speaking Text (if you are using Mail for example, look under the Mail menu next to your Apple menu).

As with last week’s tip, this trick only works in Cocoa apps. If you are using an Adobe or Microsoft program where this doesn’t work, just paste the text into a new TextEdit document and have your Mac read from there.
