Do Excel keyboard shortcuts work on the iPad app or web version using my iPad Air 5?

I just bought an iPad Air 5 and one of the things I’m using it for is some Excel work. I’m currently using a Logitech K400 Bluetooth keyboard with it (not iOS exclusive, it’s compatible to other devices like my Lenovo ThinkPad; here’s a link to the device - https://www.logitech.com/en-ph/products/keyboards/k400-plus-touchpad-keyboard.920-007166.html). I’ve noticed a lot of the keyboard shortcuts I use don’t work on either the app or the live web version of Excel (I have a premium Microsoft 365 account). I was wondering if the shortcuts don’t work because of the Excel iPad app itself or if it has something to do with the keyboard i.e. if I buy an Apple keyboard or if I use my iPad with the Magic Keyboard case, will I be able to use the shortcuts?

Some sample shortcuts/keys I’ve found doesn’t work or doesn’t work like it would in the Excel desktop version:

- CTRL + down arrow to get to the next cell w/ data

- All arrow keys to go to the next cell (only in the browser version; I can use the arrow keys to switch cells in the iPad app)

- F2 function key to edit the data in the cell

- CTRL + “C” and CTRL + “V” to copy and paste data

- CTRL + space bar and CTRL + SHIFT + “=“ to highlight a row and add a new row next to it
