Hah!

I just noticed that the ability to delete using the keyboard (Alt-E, D) is available in pretty much all modules EXCEPT 2023 T1

I was working on a 2022 T1 and was using that shortcut... and suddenly realized just that.. I was using that shortcut. It works in 2022 T1 module (when I look at the Edit menu the D in the word Delete is underscored, indicating that the function exists). And looking further this is the case with most modules

So the inability to use this function appears to be in the 2023 T1 module only
