Auto insert time in Pocket Excel

I can insert date with cntl+; from the onscreen keyboard, but cannot find a way to autoinsert time from onscreen keyboard. I haven't used this site before, so please excuse me if I'm in the wrong place. Thank you.

Wow. Thanks for the quick response.

Yes, I misspoke.
Using the onscreen keyboard, I can autoinsert the date using ctrl+:, the same as with the external keyboard.

Using the external keyboard, I can autoinset the time using ctrl+shift+;. This doesn't work using the onscreen keyboard.

One command is for date, another for time.

Thanks again.
