SUM function shortcut

How can I place the SUM function onto the formula or status bar? It would just be so much easier to do that than go through the functions side bar each time.

  1. The SUM() function is present in the formula bar as the icon showing the uppercase Greek “S” (Sigma, “Σ”)
  2. I never use the icon, but type the “=” and the three-letter-name.
  3. You may also want to know the names and parameter sequences of that couple of functions you are using on a regular basis. Typing is much more convenient than clicking around and searching the ‘Function Wizard’.
  4. That tool is mainly of use to get a structured view of nested expressions when debugging or enhancing a sheet. Use it as an editor.
