Eclipse has that \"+/-\" on the left to expand and collapse blocks of code.
I\'ve got tens of thousands of lines to go through and would really like to just collapse
There is a hotkey, mapped by default to Ctrl+Shift+NUM_KEYPAD_DIVIDE.
You can change it to something else via Window -> Preferences, search for "Keys", then for "Collapse All".
To open all code blocks the shortcut is Ctrl+Shift+NUM_KEYPAD_MULTIPLY.
In the Eclipse extension PyDev, close all code blocks is Ctrl + 9
To open all blocks, is Ctrl + 0
