IntelliCommand - an extension for Visual Studio 2010/2012/2013 which helps to find the short keys. It shows the help windows with all possible combinations when you press Ctrl or Shift or Alt or their combinations (hold it for about 2 seconds to see this window). Also it shows the list of possible combination when you press first combination of chord shortcut keys, like Ctrl+K, Ctrl+C (this combination comments selected text in editor).

Known issues:

• After you change shortcut keys you need to restart Visual Studio. Intelli Command can crash Visual Studio in this situation.
• Extension can not work on non-EN Windows or non-EN Visual Studio.
