Hello out there,
I am writing a test program for a text widget and came across the
problem to test its behaviour wrt special keys (ctrl, up, down, etc.).
I have no idea how to feed those into my widget.
Any help or advice will be greatly appreciated.
Best regards
Helmut

What do you mean by feed?

The keys you list (ctrl, up, down) are either modifiers or else have special
bindings (eg movement). The Control modifier key when applied to regular keys
has special bindings (like movement or some other function, like Copy or
Paste). What exactly are you trying to test?

There is a file in the Tk library (on my Ubuntu system is is in
/usr/share/tcltk/tk8.6/) named text.tcl which contains all of the default
bindings for the text widget, along with the helper functions that they use.

Perhaps via "event generate"?

I think he is looking for the [event generate] command.

Hello Rich,
yes, this seems to make it. It is a bit unfortunate that (from the
manual): Certain events, such as key events, require that the window
has focus to receive the event properly.
But with a bit of juggling with 'after' I think I will get it to work.
Many thanks to all who responded.
Helmut
