Issue
I'm looking for something like (setq show-trailing-whitespace t) in emacs, where all of the trailing whitespace is blindingly clear, ie highlighted. My searches for this kind of option have mostly turned up examples of removing all trailing whitespace, which is not at all what I'm looking for.
Solution
Click on:
Window > Preferences > General > Editors > Text Editors
Then click on the link "whitespace characters" to specify what should be shown.
