Scale fix toggle

A MQL5 script that will toggle (on/off) 'Scale fix' in the properties menu. (I want to use a script so that I can assign a hot key)

For example (and to fulfill the 30 word requirement). I drag the script to my charts. I assign CTRL X. When I enter CTRL X 'Scale fix' turns on and when I enter CTRL X again 'Scale fix' turns off.
