If you type in the key of an issue, you will jump straight to that issue. You do need to use the correct case, as JIRA will translate your search into the correct case. For example, if you type in 'abc-107', you will get redirected to the JIRA issue 'ABC-107'.
should be "You do not need to use the correct case"

On http://www.atlassian.com/software/jira/docs/latest/dashboard.htm:
The "Add new portlet" link in the top-right corner of the dashboard can be used to add a porlet to the dashboard page.
should be portlet, not porlet
