Can we trap the keypress for PF12 in an Indicator or Expert

 
I am using PF12 to scroll forward one bar on my chart and would like to be able to capture that event in an indicator or expert in order to control a second chart to keep them in sync. However, I find that there is no keypress event generated for the pressing of PF12. Is there any way to capture this event in mql code? Or is there a better way to keep charts in sync for scrolling?
