select source target and hit F3 for concordance search (Studio 2021)

Hi,

Yesterday I tried to set up an AHK script to switch to source segment and then select whole string and send it to concordance search (F3) when hitting CTRL+F3 but I just could not get it to work. How can I get this done?

^F3::
Send, {F6}
Send, !{F2}
Send, ^a
Send, {F3}
Return

Best regards,

Pascal
