I have reviewed the messages related to shortcuts and can't find the following.
I am using Excel 2000.

I selected a cell, for example D3, extended the selection to the whole row,
using Shift-space and then deseleted column A, all with keyboard actions.

No macros, no mouse actions were involved

After that, I could use Alt-E,D to delete the selected cells and arrow kets
to answer the pop-up asking what to delete or how to shift the remaining
cells.

But now I cannot repeat the "deseleted column A" action.

What is the keyboard combination to do this?

Thanks,
