Why have I got red lines around my cells

Please help

Hello,

yes - you probably inadvertently typed CTRL+SHIFT+C which turns on Edit -> Track Changes -> Record. To disable do the following:

  • Type CTRL+SHIFT+C once more (or use menu path mentioned above) to turn off Track Changes feature.
  • Confirm the exit.

Hope that helps.
