I tried to achieve this recently, and discovered that IDLE ignores
configurations for Ctrl+k. Ctrl+k kills a line in IDLE no matter which key
bindings you use, since this is a default key binding of Tkinter's Text
widget which is used by IDLE.

What would need to be done is to disable/override the Text widget's default
key binding - I don't know how to do this, I tried a bit but failed. With
this done, we would need to bind Ctrl+k to a new "kill line" function, which
removes the current line and puts it into the clipboard. This
could implement Emacs-like behavior, where subsequent lines killed are added
to the clipboard instead of replacing it.

So, first and foremost - does anyone know how to overcome the Text widget's
default binding for Ctrl+k?

Press and hold down SHIFT, move the cursor to the other end of the region
you wish to select, release SHIFT. (This is quite standard and works in most
text-editing apps.)

Thanks very much

Simply use the Options / Configure IDLE / Keys dialog to rebind Ctrl+k
to a new event you will define.  That will shadow Tk's kill binding, so
long as you end your method with 'return "break"' so the Ctrl-k won't
get passed to Tk.

Then implement a method in EditorWindow to select from the insertion
point to the end of the line and call EditorWindow.cut() (or copy that
code :) to get it into the clipboard.

Should work.  Send me a patch :-)

Subject: [Idle-dev] Scroll using mousewheel
Message-ID: <Pine.GSO.4.60.0610231433350.624@liman1b>

Hello all,

How do I scroll in the editor and shell using mousewheel?

I can scroll using the mousewheel only when the cursor is over the 
scroll bar on the right.
