Lost the ability to fold code in eclipse

Method 1:

Window -> Preferences -> Java -> Editor ->Folding

Method 2

ctrl + NUMPAD-/

Method 3

Right-click where line-numbers are (should be). Go to Folding -> Enable Folding.

Folding is configured under Window -> Preferences -> Java -> Editor ->Folding

The Preferences window has a search box - very useful to find even the most obscure options.
