That did it, thanks! New function looks fine, but not something I need, so happy to get my hotkey back :)

Just upgraded TCC19 to TCC23. I use the F5 hotkey alias often, but seems my alias no longer works due to a new built-in functionality for F5 to "Call the browse files dialog" For example.. "alias @@f4 echo F4" - this works, it echos F4 "alias @@f5 echo F5" - this doesn't work, it brings up...
