Here's a little productivity tip if you do a lot of in-browser text editing.
If you ever get annoyed that the tab key moves your cursor to the next form field when you are editing a text-area in a browser, download this Chrome extension.
That extension will allow you to use the tab key to indent however many spaces you specify.
This is especially useful if your writing code in markdown format where code lines need to be indented by 4 spaces. Having to hit the space key 4 times for every line of indention and not having an auto-indent feature is a killer time-waster.
