How to setup a shortcut key for a custom application or program?

[mauja]

i have developed an appliceation to find a word on a web page in c#. i want it to run on pressing ctrl+some key pressed. How to make that code run with this key shortcut?
(as normal ctrl+f runss). Is there any way to do that?

If your application is an .exe file, I don't think you can run it from a shortcut simple as CTRL+key.
But you could add a windows shortcut (Properties window of your .exe) that will be CTRL+ALT+key.
