Fill Cell with Colour in Libre Office - Keyboard Shortcut

I do a lot of things in LibreOffice Calc and it involves changing background colour of cells. I needed some keyboard short cuts and found it here. Thought might be useful. Press Ctrl+1 to invoke format cells dialogue box. Use Tab or Shift+Tab to navigate. If you use it often it opens in the last tab you left, making it easier to use. Try keyboard short cuts. They make life simple.
