Calling Help file with F1

I have  a help file. I can call it using the winhelp... or application.help command, but how do I associate the F1 key to call the help file?

Thanks

You create a help file by compiling the hpj file. In order to connect a certain field in a delphi screen to a certain help screen you must declare the [MAP] section in that hpj file .

Each screen in the help file has a uniq name which is described by declaring a footnote in the rtf file.

Under the [MAP] section you write all these uniq names + space or tab + a uniq number declared by you. This number is the HelpContext number. This should look something like this:

[MAP]
Name1 1
.
.
CustomerAccount  100
InvoiceNumber  101
.
.

Then you recompile the hpj.
For example If the user is focused on a control named 'Edit1' and by pressing F1, you want the help screen of the customer account to apear, then you should set:
Edit1.helpContext:=100;
