How to write in multiple lines simultaneously in Matlab Editor ?

I have seen the new funcionalities in version 2021b and it appears that you can put the cursor in multiples lines for writing code.

This feature works only in adjacent lines.

Hold down the 'Alt' Key and drag over multiple lines with the mouse.

You should then see multiple highlighted characters.

This feature only works on Matlab 2021b!

if I recall correctly it worked in Livescript for a version before that, but I do not recall when it was introduced in Livescript.

The multiline editing in matlab is really nice, but is there any way we can get the arrow keys to work with it? What i mean is, When the alt key is held and we press the up and down arrows, additional lines should be added to our selection. This would same me some significant time swapping from keyboard to mouse. Also, on a laptop the arrow keys are far more reliable for accuarte input that trackpads.

If there is an existing way to do this i'd love to know! Thanks for considering!
