This feature is only supported in the Ultimate edition.

The following is only valid when IdeaVim Plugin is installed and enabled!

Before you start

Make sure that:

You are working with IntelliJ IDEA version 15.0.0 or higher. If you still do not have IntelliJ IDEA, download it from this page. To install IntelliJ IDEA, follow the instructions, depending on your platform.

Downloading and installing IdeaVim plugin

On the toolbar of the IntelliJ IDEA main window, press Ctrl+Alt+S to open the Settings/Preferences dialog, and then click Plugins settings.

You see the list of plugins currently installed on you computer. However, the IdeaVim plugin is not among them. Click the button Browse JetBrains plugins. IntelliJ IDEA shows the contents of the huge JetBrains repository... you can type the word "vim" in the search field to narrow down the list:

After installing the plugin, it actually becomes available after IntelliJ IDEA restart.

What happens to IntelliJ IDEA's UI after restart?

First, on the Tools menu, a check command Vim Emulator appears:

After IntelliJ IDEA restart, this check command is selected. You can disable Vim by clearing this check command.

Second, in Settings/Preferences dialog, an additional page Vim Emulation appears after restart.

Configuring shortcuts

Both Vim and IntelliJ IDEA are keyboard-centric. With IdeaVim plugin, it is quite possible that IntelliJ IDEA's keymap runs into a conflict with the Vim keymap. That's why IntelliJ IDEA allows you choosing which keyboard shortcut you prefer for a certain action. This is how it's done.

Open Settings/Preferences dialog, and click Vim Emulation:

In the Shortcut column, select the shortcut you want to configure. Next, in the Handler column, click the corresponding cell, and see the drop-down list of three possible options (Undefined, IDE, Vim):

If you choose IDE, it means that the IntelliJ IDEA's shortcut for this particular action is enabled. When you press, say, Ctrl+Z, IntelliJ IDEA silently performs its action.

If you leave the handler undefined, then, on pressing the shortcut, say, Ctrl+B, IntelliJ IDEA shows the banner.

You can choose to redefine this shortcut as an IDE shortcut and thus accept the IntelliJ IDEA's keymap. To do so, click the link IDE shortcut.

If you click the down arrow and then the link Vim Emulation, then IntelliJ IDEA will show the Vim Emulation page of the Settings/Preferences dialog.

For the purposes of this tutorial, click the link Vim Emulation. Then, when you press Ctrl+B, IntelliJ IDEA will perform the Vim action for this keyboard shortcut.
