looking for syntax for .axisrc file to bind a key to run O code (.ngc file)

I am looking for the correct syntax to use in an .axisrc file to bind a key to run O code (.ngc file)?
I have been googling this for the past couple of days and cannot get anything that works. I am using LinuxCNC2.8.
I have setup Z touch off by following this 7xcnc.com/software/probing/z-touch-plate/

I currently have the following line in my .axisrc file, which does not work
root_window.bind("<XF86HomePage>", c.mdi("o100 call"))

If I manually run o100 call in MDI it works
I have a PYVCP button in AXIS and clicking on that works too.
I just can't get it to launch of keypress on my wireless keyboard/pendant

I tested the key binding using this
root_window.bind("<XF86HomePage>", "destroy .") and the key bind works,
I just need to get the key bind to launch the o100 file, all suggestions greatly excepted

Maybe this helps, i think it worked for this member.

You may need to call a function then put your commands in the function, something like:

def my_button_function(event):
    ensure_mode(linuxcnc.MODE_MDI)
    c.mdi("o100 call")

root_window.bind("<XF86HomePage>", my_button_function)

does all of that go in the .axisrc file?

Yes and in that order.

this worked perfectly, thank you
