1. Any file in your workspace
2. Any Python Token
This is actually what I use most as a single place can be used to filter for package names, classes, methods and attributes inside your own projects or any other package in Python itself. Also, it allows for advanced filtering, so, you can search for tokens only inside a package (i.e.: dj.tz filters for any 'tz' token inside django in the example below).
3. Quick Outline (current editor)
4. Selection History
5. Open files
To filter through the open files you can use Ctrl+E: a dropdown will appear and from there you can filter through its name and you can close existing editors using Del from that dropdown too.
6. Go to previous next token (class or method)
Ctrl+Shift+Up and Ctrl+Shift+Down allows you to quickly navigate from your current position to the previous or next method (selecting the full method/class name).
7. Navigate through occurrences and errors in the file
Ctrl+Dot allows navigating through occurrences and errors found in the file, so, in the case below we'll navigate through the occurrences of 'func'.
8. Go to some view/menu/action/preference
Ctrl+Shift+G will make a search showing all the references to the token under the cursor (and the search view where results are shown can be navigated with Ctrl+Dot).
10. Go to definition
Just press F3 or Ctrl+Click some available token and go directly to the selected place.
11. Hierarchy View
12. Show In
Alt+Shift+W allows you to see the current file in a given place (such as the PyDev Package Explorer or the System Explorer from your OS) or your current class/method in the Outline View.
Ctrl+L allows you to navigate to a given line in your current editor.
Ctrl+Q goes to the place where the last edition was made.
Ctrl+F6 navigates through the opened editors. In LiClipse Ctrl+Tab is also bound to it by default-- and I suggest you also add this binding if you aren't using LiClipse :)
Ctrl+F7 navigates through opened views (i.e.: Package Explorer, Outline, etc.)
Ctrl+F8 navigates through opened perspectives (i.e.: PyDev perspective, Debug perspective, etc).
Ctrl+F10 opens the menu for the current view (so you can select filters in the Package Explorer, etc.)
F12 focuses the editor (so, you can go from any view to the editor)
Ctrl+H Opens the search dialog so you can do text searches
Ctrl+Shift+L twice goes to the keybindings preferences
