Change Time Frame Hotkey for MT4?

[supercallim]

Hi!

Instead of hovering my mouse to change the time frame, is there a single hotkey i can set or press to change time frame? 

If yes, can i also choose if this hotkey changes timeframe for all my charts or just the chart im viewing? thank you!

for Mt4

You can edit the switch cases with :
