If you put the following lines in ~/.vimrc, you can press F12 in both normal
and insert mode to remove all trailing whitespace from the file currently
edited:

  " Strip trailing whitespace (and keep the cursor position)
  command! StripTrailingWhitespace normal mx<Enter>:%s/\s\+$//<Enter>:nohlsearch<Enter>`x
  nnoremap <F12> :StripTrailingWhitespace<CR>
  inoremap <F12> <C-O>:StripTrailingWhitespace<CR>

Good luck! :)
