In Excel we have some Alt shortcuts like:
- Alt - E - S - V: paste special value only
- Alt - I - R: insert a new row
In Google Sheets they can also be used. When I press Alt + I for example, I see this popup at the bottom:
With this turned on, I can use the above-mentioned Alt shortcuts. However, there are some of my computers (Windows 10) where turning this option on or off have no effect. The above Alt shortcuts cannot be used. There is nothing special about this computer: running Windows 10 latest version, latest Chrome.
