axis.tcl keyboard shortcut problem

Hello my friends.

I'm trying to add new keyboard shortcut to axis for controlling the spindle override.

In axis.py file with the codes below,

root_window.bind("2", lambda event: set_rapidrate(20)) --- controls the rapidrate
root_window.bind("3", lambda event: set_feedrate(20)) ---- controls the feedrate
root_window.bind("4", lambda event: set_spindlerate(20)) ---- not controls the spindlerate

Do you have any idea why I cant control the spindle rate by pressing the keyboard buttons ?

I solved the problem guys.

In axis.py file we need to add these lines;

and for controlling the spindlerate over keyboard ;
"1" for keyboard shortcut, and 30 for the rate....

probably correct to write this in ~.axisrc
