I've downloaded the Manual pages to my Hard Drive and would like to access them via the Help>Manual menu. Is there a way to do this either through Prefs or the source code?

    $\begingroup$ This is certainly possible be modifying the source code, unfortunately this isn't configurable through the user preferences. The operator WM_OT_url_open_preset is implemented in wm.py. $\endgroup$

Two ways I can see to achieve this.

1 Manually edit the UI script

Either manually edit the space_topbar.py topbar UI file traditionally found at Blender_2.82\2.82\scripts\startup\bl_ui\space_topbar.py and type in an entry there to link to your local file.

You can optionally remove the online manual entry from there and replace it with an instance of wm.url_open operator pointing to your local file. Just copy one of the existing templates and modify it to your own use.

This is a quick and dirty solution, allows removing the existing entry, but is less maintainable, since it will likely not survive a software update nor is it easy to port to other installations.

2 Create a script or addon

Create a script that registers a new menu entry with a link to your own file. Easiest is probably to use wm.url_open operator pointing to your local file.

enter image description here

import bpy

def menu_func(self, context):
            "wm.url_open", text="Local Maual", icon='HELP',
        ).url = "Z:/Applications/Blender/Documentation/Blender_Manual.pdf"

def register():

def unregister():

if __name__ == "__main__":

As far as I know this won't allow removing the existing entry, but you can have the addon under, several instances, and can easily be reinstalled after software updates.
