If you haven’t discovered the Press This (formerly known as Press It) posting shortcut for WordPress yet, now is the time to do it. WordPress 2.7 has moved the bookmark from the Write Post page- to the Tools menu- where it should have been all along.
Here is the official description.
Press This is a bookmarklet: a little app that runs in your browser and lets you grab bits of the web.
Use Press This to clip text, images and videos from any web page. Then edit and add more straight from Press This before you save or publish it in a post on your blog.
Drag-and-drop the following link to your bookmarks bar or right click it and add it to your favorites for a posting shortcut.
The key to using PressThis is to make sure you have isolated an article to a single URL- and then highlight the text you want to discuss- hit your Press This bookmark that you’ve saved in your Firefox Bookmarks toolbar- and the text you highlighted will be put in a floating window- complete with a link back to the source. Blockquote what you Pressed- and write an open and close- and Voila! Instant high value content with less effort.
