Additional Hotkey Options

Hi, is it possible to add an option so hotkeys can be used to change a charts timeframe when it is set on a regular candlestick chart e.g. set a hotkey so that when i press "CTRL+3" the chart changes to 30mins or if i press "CTRL+6" the chart changes to 60mins? 

Also, can a hotkey be added to add or subtract contracts when the trading sidebar is open? e.g. set hotkey to "+" to add additional contracts and "-" to take away contracts?

Thanks
