Script needed to press keyboard keys by clicking on chart

on my MT5 there are 5 open charts.

I like to have a button on the right/top side of the chart and then following keyboard shortcuts will be executed: CTRL+F6.

(script will be applied to all open charts)

script is needed, because I access MT5 via remote without keyboard and I like to switch trough all open charts.

Thanks for your help, Tom.
