This cheatsheet was created to remember commands which I widely use in IntelliJ IDEA. Most of the shortcuts are similar to the shortcuts for Visual Studio (see my previous post), but still some minor differences are presented. Other default shortcuts for IntelliJ Idea can be found on jetbrains website.

To assign shortkeys to commands you have to open Settings/Preferences dialog (Ctrl+Alt+S) and select Keymap.
