I'v seen this also:
this must be a bug.

next time, I start:

_tkinter.TclError: bad event type or keysym "tab"

(On Windows)
I discovered, looking in C:\.idlerc\config-keys.cfg

there was the entry
dedent-region = <Shift-Key-tab>

with an editor you can change it to uppercase:

dedent-region = <Shift-Key-Tab>

then it works again.
