Help Lookup is available through the Maple code hover.
It allows you to look up help for Maple symbols on the Maplesoft web site.
To use help lookup
Hold down the Ctrl Key (Windows, Linux) or Command Key (Mac) and move the mouse cursor over a Maple element you want to explore.
A blue line will appear under the element. Click the element.
A web browser is opened that shows the result of the search on the Maplesoft site.
From this you can follow links to get more detailed information about the element.
