Using Windows XP for Professionals.
SISTER's computer uses same.
On her computer I can go to my AOL email, click on "From" column to organize all senders
alphabetically in "batches".
Then, on her computer, I can put a check in the box next to the first email of the chosen
batch, THEN HOLD DOWN THE SHIFT KEY, then check the last email in the batch.
This highlights AND PUTS CHECK MARKS next to all the emails in the batch. Quickly.
Then, I can use the mouse, left click ANYWHERE IN THE BATCH REGION, and drag
all those emails into their folder (which are all displayed in a column to the left of the screen).
When hitting the left button on the  mouse to drag-and-drop, a little FLAG POPS up that
even says exactly how many emails I am moving.
THIS DOES NOT HAPPEN ON MY COMPUTER.
Nothing in "settings" or "shortcuts" within AOL addresses this.  My sister says its not
a function of the email program, but rather of WINDOWS itself.
How can I make this functionality happen on MY computer?How are you ACCESSING AOL's mail? Through a browser or mail client or what? That's what will affect this in the way you're referring to, not the operating system.Are you and your sister using two DIFFERENT versions of AOL?
