[Blindmath] A Question About Excel and JAWS

[Trevor Attenberg]

                Hey Blind  Mathemagicians list,

I have two questions for the knowing that I wasn't able to answer via the
Blind Math List archives. They should be pretty easy.

First: is there a way to drag a formula through a column, row, or block of
values using JAWS on a laptop? You know how a mouse user can drag a formula,
and thus not need to type said formula over and over again? Never have I
figured a means or analogue for this by way of JAWS. JAWS manuals do provide
a dragging command, but this hasn't worked for me. Perhaps I am missing
something. I've tried with and without the JAWS cursor.

Second and finally, I would like to know how to independently retrieve
regression stats within excel. I am able to generate biplots etc. from the
menu bar, but I haven't been able to figure out how to find R2 values and
the like. This seems like pretty important stuff. Perhaps I should simply
learn to do it in R? There's a thread that discusses Excel and regression
from close to a decade ago, but this doesn't seem particularly
helpful-perhaps it is no longer accurate.

Thank you for your time, and in advance for your help.

Trevor
