Using FakeVim Mode

在 FakeVim mode, you can run the main editor in a manner similar to the Vim editor. To run the editor in the FakeVim mode, select Edit > 高级 > Use Vim-style Editing or press Alt+V,Alt+V .

Supported Modes and Commands

在 FakeVim mode, most keystrokes in the main editor will be intercepted and interpreted in a way that resembles Vim. Most of the supported commands can be followed by a motion command or executed in visual mode, or they work with registers or can be prefixed with a number of repetitions.

The following sections describe the commands emulated in the supported modes and how they diverge from Vim in functionality:

• Normal
• Visual
• Command line (:)
• Insert and replace

For more information on using Vim, see 文档编制 on the Vim web site.

• . repeats the last change
• /search , ?search , * , # , n , N - most of regular expression syntax is used in Vim except that \< and \> are the same as \b in QRegExp
• @ and q (macro recording and execution) special keys are saved as <S-Left>

Mapping FakeVim Commands

To map commands entered on the FakeVim command line to actions of the Qt Creator core, select 工具 > Options > FakeVim > Ex Command Mapping .

To map user commands to keyboard shortcuts, select 工具 > Options > FakeVim > User Command Mapping . The user command mapped to the shortcut is executed by FakeVim as if you were typing it (as when replaying a macro).
