SilverBullet has a basic Vim mode. You can toggle it using the ${widgets.commandButton("Editor: Toggle Vim Mode")} command.

In addition, it supports various ex commands that you can run as you would expect, for instance: :imap jj <Esc>.

The CONFIG file can also be used to define and extend these commands. It supports the following:

• Key unmapping - disable existing keybindings
• Custom mappings - using map and noremap
• Ex command definitions - map custom ex commands to built-in or custom SilverBullet commands

To manually reload the vim section of your CONFIG, use the ${widgets.commandButton("Editor: Vim: Load Vim Config")} command.

Configuration

Using Space Lua:

config.set {
  vim = {
    unmap = {
      "<Space>",
      {
        key = "<C-c>",
        mode = "insert",
      },
    },
    map = {
      {
        map = "jj",
        to = "<Esc>",
        mode = "insert",
      },
    },
    noremap = {
      {
        map = "<",
        to = "<gv",
        mode = "visual",
      },
      {
        map = "<Space>ff",
        to = ":findfile<CR>",
        mode = "normal",
      },
      {
        map = "<Space>rc",
        to = ":runcommand<CR>",
        mode = "normal",
      },
    },
    commands = {
      {
        command = "Navigate: Page Picker",
        ex = "findfile",
      },
      {
        command = "Open Command Palette",
        ex = "runcommand",
      },
    }
  }
}
