[visual-studio-code] Remove trailing spaces automatically or with a shortcut

Not only can you change the Visual Studio Code settings to trim trailing whitespace automatically, but you can also do this from the command palette (Ctrl+Shift+P):

Command Palette: Trim Trailing Whitespace

You can also use the keyboard shortcut:

  • Windows, Linux: Ctrl+K, Ctrl+X
  • Mac: ? + k, ? + x.

(I'm using Visual Studio Code 1.20.1.)
