Online help is available for each tab found in HotApoc.

The HotApoc is laid out in a series of tabbed notebook pages. Each page contains a collection of controls which govern HotApoc's behavior.

Help is available from within HotApoc by hovering over the control in question. Help messages for that control will appear in the help panel at the bottom of the screen. If you cannot see the help panel, try resizing your screen to be a little taller.

By clicking on the links found on the left hand side of this screen you can read the help for all tabs found in HotApoc.

For each tab there are two parts to the help: a general description of the tab and a screen shot of the tab itself.
By clicking on individual controls in the image in the screen shot, help on that control will appear above the image.
To flip between these two parts click on the link at the top of the page.
