one example of my problem is choosing "View -> Quick Definition Lookup" works like expected, but the keyboard shortcut "Ctrl-Shift-I" (which is "stolen" by ICQ and unfortunately not disableable anymore) doesn't work. I've seen this with others too if Windows itself uses the shortcut. E. g. I assigned Ctrl-Alt-I to start up IDEA and thus the shortcut isn't delivered to IDEA and so the "Auto-indent lines" action which has the same shortcut is not useable. If I press it, nothing happens. And it is also not delivered to IDEA. The action is not invoked and if I try to assign this shortcut to an action, this doesn't work either, because the shortcut doesn't arrive at IDEA.

My request is the following:

• Check on startup of IDEA which shortcuts are used by the operating system or other programs so that IDEA cannot receive them.
• Checked if these unreceivable shortcuts are used in IDEA currently and warn the user that the shortcut will not work in IDEA currently.
• Provide a list to the user, which shortcuts are unreceivable currently, so that he doesn't wonder why nothing appears in the input box of the options dialog where you can configure the shortcuts when he presses an unreceivable shortcut as I did.
• If possible, also tell the user which program blocks the shortcut so that he knows which program he has to shut down or reconfigure.
