I have managed to successfully edit the customer navigation bar by editing the file ZZZAAuto.pm located in "otrs\Kernel\Config\Files", so that the companytickets link has been removed and I have moved the logout button to the right instead of it being on the left. I have also added a new button that links to a help manual that I have written for all of our users. However I am having a major problem getting it to link to this new webpage.

My understanding is that when a user clicks a button on the navigation bar it links to a module in "otrs\Kernel\Modules" via the line: 'Link' => 'Action=CustomerPreferences'. So in this example it loads the CustomerPreferences.pm file that does lots of advanced things that I have no clue about. Somewhere in this file there is a line or lines that tells it which template to use for the layout, in this case I think it is the CustomerPreferencesForm.dtl file located in "otrs\Kernel\Output\HTML\Company" (I have a customer interface called Company other wise replace Company with Standard).

So, I have tried to create a .pm file called Manual.pm and the 'User Manual' button in the nav bar links to this file via the line 'Link' => 'Action=Manual'. However I am stuck because I have no idea how to get this .pm file to link the index.html page of the manual as this is a bit too advanced for me. I can't seem to test it either because when I click the User Manual button I get the error message: "Error: Module Kernel::Modules::Manual not registered in Kernel/Config.pm!".

Secondly, what do I need to put in the Manual.pm file so that it links or redirects to the index.html page of the user manual? or can I use the line in the ZZZAAuto.pm file 'Link' => ' ' to link to it somehow, maybe by using the direct link? The problem with this is that when i click the link it sends me to http://wbhapp/otrs/Customer.pl?http://wbhapp/SupportDesk/index.html. Can the baselink be ignored at all?
