c# - Call a method when specific key combination is pressed anywhere in the app, as long as application is currently focused window -

-

my objective allow users of app bringup i'm calling debug console pressing ctrl + f11 on keyboard.

simply put, need call toggledebug(); method, enable debug tracing code , display window. i'd application @ point when ctrl + f11 pressed, regardless of user has focus cursor long application focused window.

my app deployed through click once -- partial trust type environment.

in old vb6 app, had been using wend loop call doevents() , windows api call... needless say, i'm hoping there better way now.

you can handle previewkeydown event of window.

public mainwindow() {     initializecomponent();     this.previewkeydown += new keyeventhandler(mainwindow_previewkeydown); }  void mainwindow_previewkeydown(object sender, keyeventargs e) {     if ((e.key == key.f11) && (keyboard.modifiers == modifierkeys.control))     {       } }
