In Google sheet 'ctrl + spacebar' is used to select the entire column of the selected cell. I have seen it working on other devices, but in "Samsung S10 Ultra 5g Book Cover keyboard" the shortcut does not function.
I have tried a simple application to test it, when compose onKeyPress handler does not receive any key input signal from the spacebar when 'ctrl' is pressed. This is very specific to the above-mentioned keyboard and tablet.
It sounds like the Samsung S10 Ultra 5G Book Cover Keyboard may have a compatibility issue with handling Ctrl + Spacebar in Google Sheets and other applications. Given that the onKeyPress handler does not detect a signal from the spacebar when Ctrl is pressed, it suggests that the keyboard firmware or Android's key event handling might be blocking this combination.
Possible Workarounds:
Use an Alternative Shortcut
Try using Shift + Spacebar (which selects an entire row) or other related shortcuts (Ctrl + A to select everything) as a workaround.
Use an External Bluetooth Keyboard
If you have access to another keyboard, test whether Ctrl + Spacebar works there. If it does, the issue is likely specific to Samsung's Book Cover Keyboard.
Check Samsung Keyboard Settings
Go to Settings > General Management > Physical Keyboard and check if any special key mappings or shortcuts interfere with Ctrl + Spacebar.
Use Google Sheets in a Different Browser
If you're using the Google Sheets app, try opening it in Google Chrome or another browser on your tablet and test if the shortcut works.
Check for Software Updates
Ensure that your tablet and keyboard firmware are up to date by checking Settings > Software Update.
Try a Key Remapping App
Apps like "Key Mapper" or "External Keyboard Helper" might allow you to remap Ctrl + Spacebar to another combination that works.
Samsung DeX Mode Test
If you're using Samsung DeX, switch between DeX mode and regular tablet mode to see if the shortcut behaves differently.
Since youāve already tested it in a simple application and confirmed that Ctrl + Spacebar is not recognized, itās likely a hardware/firmware limitation rather than a Google Sheets issue.
