> but not with binding to modifier-up/down.

I cannot reproduce. I have tested on both Windows and Linux and found I could 
successfully change to (and use) the modifier-up/down bindings both through the 
Keys page of the configdialog and by editing the keys def. There was no 
traceback on either platform. @wyz23x2, can you reproduce this problem?

My personal preference for the new bindings, when tested, was alt-up/down as it 
is most similar to the existing bindings. Also, control-up/down is used in 
other apps for moving the cursor multiple lines at a time and shift-up/down (at 
least in my mind) seems like a weird/random choice. Terry, I don't know what 
you have in mind, but I think these bindings should be in addition to the 
existing ones rather than instead of (I also tested this and found it to work 
correctly).

Yes, history works fine with the current bindings to alt-p and alt-n, or with 
binding to up or down, but not with binding to modifier-up/down.

[issue41075] IDLE: Better support history navigation

Terry J. Reedy  added the comment:

History and up/down is apart of #2704.  It has patches that include the up/down 
change, but I don't expect to use any of them as they are.

I tried Shift/Control/Alt - Up/Down and none worked.  Rebinding just Up/Down 
did (in Shell only, leaving up/down unchanged in Editor).  But not having 
up/down work to move between lines in the Shell multiline statement entry area 
is not acceptable to me.  I don't know if modifiers can never work with up/down 
or if there is something that would make it work.
