Alt-PgUp/PgDown don't do anything with my kbd layout.
The "Go to Next Bookmark" option from the context menu (right-click) only allows me to jump between bookmarks within a single file.
So, if I have a bookmark in a different file, I have to manually select that file first and then use the "Go to Next Bookmark" option to get to it.
This is a problem for me at the moment where I'm working on a large project that was given to me and I don't know what each file does. So as others explain things to me, I would like to be able to set bookmarks so I can find the code/definitions I need later.
Perhaps it's better to leave this thread as a feature request since you're no doubt busy with other things.
Cheers,
