The Navi plugin includes functionality for quick and easy navigation between pages in Confluence (forward/backward/to child pages) without using the built-in page tree.
Description:
Use the far left and right buttons to switch between pages on the same level.
For example:
Use single left and right arrow keys to go to +1 and -1 pages (go through child pages)
The pages open for editing also contain Navi plugin buttons for easy switching between pages:
Note:
when creating new pages (which have not been saved yet) - plugin buttons are inactive.
