Hello, TG#66
Welcome to Microsoft Community.
I realize that you have encountered a problem with using Ctrl PageDown to navigate to next page in Word. I understand how you feel.
I have tried to reproduce your issue here.
**1 ->**When I set Ctrl + PageDown as the shortcut for the NextPage command, I encountered the same situation as you:
When I press Ctrl + PageDown, Word only navigates to the next page, but the cursor does not move. The cursor appears only when I click on the next page.
2 -> When I set Ctrl + PageDown as the shortcut for the BrowseNext command, the situation is different:

So, please try setting Ctrl + PageDown as the shortcut for the BrowseNext command instead of the Next Page command.
- In Word, click File > Options > Customize Ribbon >Customize.

- Select All Commands in Categories on the left, find NextPage command in Commands list on the right. Click Ctrl + PageDown in Current keys, click Remove.

- Find BrowseNext command in Commands list on the right. In the Press new shortcut keys box, press Ctrl + PageDown, click Assign.

- Click close > Ok.
- See the effect.
