changing timeframe

 

hi
I was up to write an indicator to help accessing the charts on full screen mode. 

on of the things I was up to do was changing the timeframes with short keys. is there anyone who can help me what are the codes to access and change the timeframes?
is there any?

 

thanks and regards 

 

NVM.

I found this indicator and it eases the work for me. thanks all
