Help Menu

Sabrina has 2 options for displaying help

Hypertext Markup Language (.html) files, such as the one you are reading now, viewed through a browser. Sabrina is configured to make calls to Netscape Navigator to display help topics (support for other browsers can probably be added).
Text-only help viewed in the Sabrina Help Window. The help text is contained in the file sabhelp

Use of html help requires entries in the Resources file.

Help Menu Entries

Contents: Displays the Contents Page (or a list of available topics for text-only help).
Context: Display help for a a selected button or window. The cursor changes to a Question Mark until a selection is made. If no help is available for a selection, Sabrina quietly exits the context-help mode. See below for how to obtain help on menu items.
Help on Help: Displays this page.
Show Popup Tips: Enables (checked) or disables (unchecked) the display of Tips that appear when the cursor enters a button or menu bar item.

Obtaining Help for Menu Items

The HELP key (if one exists) or F1 (unless it has been remapped to perform other functions) invoke help for the item that has the focus when the key is pressed.

To obtain help for a menu item, the menu must be traversed using the keyboard rather than the mouse:

Open the menu by a left mouse click on a menubar item or alt plus the appropriate mnemonic.
Navigate around the menus using the arrow keys.
Press the HELP or F1 key when the desired item is highlighted.

There is no help for the cascade buttons that display a submenu.

Obtaining Help for Other Items

Dialogs: Select the Help button at the button right of dialog windows.
Listing Windows: Select the Help button at the bottom of the File Listing, List, and Query windows.
Graphics and Main Window: Use the HELP or F1 key when the cursor is in the window or click on the window in the context-help mode.
Action Buttons and Particle Track ToolbarButtons: Use the HELP or F1 key when the button is highlighted or click on the button in the context-help mode.
Question Dialogs: Sorry

Browser Tips

The first call to the html browser (eg. Netscape Navigator) will take a few seconds while Sabrina asks each window "Are you Netscape?".

If the browser is not running when a help topic is requested, Sabrina will ask if it should be started. If the answer is 'Yes', wait until the browser has started before reentering the help request (Sabrina does not remember the original request).

The browser window is raised to the top whenever a help request is made. If it is iconified, it is de-iconified.

Ignore any occasional complaints from the browser about protocols, etc.
