I too prefer keyboarding over mousing as it's faster. I use Open Office, which is very similar to Excel (you can save files in Excel format if needed). Anyway, if you're entering data across several columns, like a date, description, and a price, then hit "Enter" and you will move down a row to the next entry of date, description, etc. If you're just entering data in 1 column, when you hit "Enter" you will move down one cell in the column.
If you want a column or row formulated for dates, go to the cell format and choose the date format you desire, such as 01/01/2025, January 1, 2025, 01/01/25, etc. Then use the paintbrush format tool to copy this format and apply it to any cell that you want the same format. For instance, if doing a column of dates, set the first cell in the column to your desired format and paint the format onto the rest of the column. Or you can copy the first cell and paste its contents into the other cells and edit the date content and it will retain the cell format.
I hope this makes sense. Been using spreadsheets for decades - they're really handy tools for so many applications.
