This is the "file" menu. It can be used to invoke\
some overall operations on the rolodex applications,\
such as loading a file or exiting.
EOF

$helpTopics[$root.menu.file_menu.index(0)] = <<EOF
The "Load" entry in the "File" menu posts a dialog box\
that you can use to select a rolodex file
EOF

$helpTopics[$root.menu.file_menu.index(1)] = <<EOF
The "Exit" entry in the "File" menu causes the rolodex\
application to terminate
EOF

In this field of the rolodex entry you should\
type the person's name
EOF

$helpTopics[$root.frame.entry[2]] = <<EOF
In this field of the rolodex entry you should\
type the first line of the person's address
EOF

$helpTopics[$root.frame.entry[3]] = <<EOF
In this field of the rolodex entry you should\
type the second line of the person's address
EOF

$helpTopics[$root.frame.entry[4]] = <<EOF
In this field of the rolodex entry you should\

EOF

$helpTopics[$root.frame.entry[5]] = <<EOF
In this field of the rolodex entry you should\

In this field of the rolodex entry you should\
type the phone number for the person's FAX machine
EOF

$helpTopics["context"] = <<EOF
Unfortunately, this application doesn't support context-sensitive\
help in the usual way, because when this demo was written Ruby/Tk\
didn't have a grab mechanism and this is needed for context-sensitive\
help. Instead, you can achive much the same effect by simply moving\
the mouse over the window you're curious about and pressing the\
Help or F1 keys. You can do this anytime.
EOF

$helpTopics["help"] = <<EOF
This application provides only very crude help. Besides the\
entries in this menu, you can get help on individual windows\
by moving the mouse cursor over the window and pressing the\
Help or F1 keys.
EOF

$helpTopics["window"] = <<EOF
This window is a dummy rolodex application created as part of\
Tom LaStrange's toolkit benchmark. It doesn't really do anything\
useful except to demonstrate a few features of the Ruby/Tk.
EOF

$helpTopics["keys"] = <<EOF
The following accelerator keys are defined for this application\
(in addition to those already available for the entry windows):
Ctrl+A:         Add
Ctrl+C:         Clear
Ctrl+D:         Delete
Ctrl+F:         Enter file name
Ctrl+Q:         Exit application (quit)
Ctrl+S:         Search (dummy operation)
EOF

$helpTopics["version"] = <<EOF
This is version 1.0.1.
