The info on this page is for OED version 0.6.0. See "Help versions" menu at top of page for other versions.
OED provides popup help (tooltips) within the web browser to help users.
Anywhere you see the "?" icon, you can click to get a popup to see help on what is near the icon. This is shown in the next figure where the "?" icon is highlighted with a blue box. The "?" icon has been clicked and the help tooltip popup is shown.
Normally only one popup is allowed but a few can be shown simultaneously. In general, there is a link to the appropriate help website page to give the user further information on this part of OED.
None at this time.
