Instead, when you modify any shortcut of a predefined keymap, PhpStorm creates a copy of that keymap, which you can configure. Another keymap specific to macOS is macOS System Shortcuts that follows the Default Mac OS X System Key Bindings conventions.Ī keymap is a list of actions with corresponding keyboard and mouse shortcuts and abbreviations. There is also IntelliJ IDEA Classic, which is a legacy keymap that resembles the default keymap for Windows. Make sure that it matches the OS you are using or select the one that matches shortcuts from another IDE or editor you are used to (for example, Eclipse or NetBeans). PhpStorm automatically suggests a predefined keymap based on your environment. To view the keymap configuration, open the Settings dialog Ctrl+Alt+S and select Keymap. PhpStorm includes several predefined keymaps and lets you customize frequently used shortcuts.
