maurice_chevalier has asked for the wisdom of the Perl Monks concerning the following question:

hail thee, monks.
platform is windows with active perl.
what i'd like to do is the following:
main part will be a perl tray-application sitting there waiting.
whenever a user marks something in another application and presses a ctrl+key combination ( i.e. "ctrl+a+b" )
i'd like to pass the marked string to the tray app for further computings.
question is how to "catch" the ctrl+key combination and how to reference the marked text ?
any tips greatly appreciated.

    Skip Perl, use AutoHotKey instead. To quote their home page:

    AutoHotkey is a free, open-source utility for Windows. With it, you can:
    • Automate almost anything by sending keystrokes and mouse clicks. You can write a mouse or keyboard macro by hand or use the macro recorder.
    • Create hotkeys for keyboard, joystick, and mouse. Virtually any key, button, or combination can become a hotkey.
    • [and a lot more that isn't relevant to your needs]
    The only "problem" is that it's syntax is like nothing you've ever seen. OTOH, (a) you can launch external programs, such as Perl scripts, without much effort, and (b) there's a forum that's always willing to help.

      I'll second that. AHK is specifically targeted for the OP use case. You can do the key monitoring, the selection grab and the pass-on-to-perl script in about one line each.

      The syntax and commands are certainly unique, so you'll want to have the AHK help file open at all times.
