I call it the AutoSum. It is one of the top 5 Excel commands. What are the weirdest names you've heard workers use for this icon?

Built a Copilot agent to search 2,500 MrExcel videos.
It works… until it doesn’t.
Finds results, builds table — then forgets how to Insert to Excel.
Icon broke it. Clipboard is the fallback.
Feels 90% done, 100% maddening.

Am I just holding it wrong?

Built a custom GPT in ChatGPT — works flawlessly.
Copied it into Copilot Studio — same setup, but… nothing works.
Why?
Provisioning delay? File type issues? Broken insert?
🎥 Flawed insight, in-progress debug:

Highlight the active cell in Beta. View, Focus Cell. Choose one of 10 colors. The highlighting is above the grid, below the drawing layer. It does not destroy any existing formatting. And, it is fast. Short video demo: youtube.com/shorts/UO2cy41rO…
