Strange behaviour of "Duplicate Area Into New Window"

Hi!

I made a custom Key Configuration (this one) that just remaps letters to make my Colemak keyboard layout act like Qwerty in Blender. So S -> R, F -> T, etc.

Now, if I press Alt+A, the add menu comes up. But after about 0.5 s of holding Shift after that, a new window pops up with the 3D view in it. I’m pretty sure that is the “Duplicate Area Into New Window” function. The strange thing is that I have not changed that hotkey; it was Shift before, and it is still Shift. If I disable that hotkey, the problem goes away. Same thing happens with Shift+S for “Selection to…” menu: If I hold shift, a new Window pops up.

So, why does this happen, even though I have not changed the hotkey for “Duplicate Area Into New Window”?

EDIT: I found out that if I remove the line
kmi = km.keymap_items.new(‘screen.area_dupli’, ‘NONE’, ‘ANY’, shift=True)
from the file, the problem does not happen. I guess that if I include it, the action is marked as “User edited” or something, and works differently.

I cannot really answer your question, but i will ask another question instead:
Maybe it’d be simpler to have your OS switch back to a QWERTY layout when using blender ?

@Gwenouille No, already have 2 layouts, 3 is a bit much.
