iKeySnail

iKeySnail provides fully-configurable hardware keyboard functionalities for web browsing on iOS (iPadOS).

The aim of this project is to provide { Vimium, Vimperator, Surfingkeys, KeySnail } for iOS. Currently, iKeySnail supports

• Hardware keyboard supported web browsing
  • Emacs-like keybindings/functionalities
    • e.g., Ctrl-Space to set mark, Meta-w to copy the selected region, Ctrl-y to yank (paste) the clipboard text
  • Vim-like keybindings/functionalities
    • e.g., j/k/h/l/g/G to quickly scroll web pages
• Link-hints (Hit-a-hint)
  • For clicking links without touching your iOS device screen
  • 
• Vertical tabs
  • We do support vertical tabs in iOS!
  • Setting config.TAB_VERTICAL = true makes tab orientations vertical
  • 
• Omnibar support
  • Work-in-progress, but we do support omnibar. By default, pressing o opens your bookmarks.

Installation

You need JSBox (https://docs.xteko.com/#/en/) to run iKeySnail. After installing the JSBox, access either of

• https://tinyurl.com/ikeysnail
• jsbox://import/?url=https%3A%2F%2Fgithub.com%2Fmooz%2Fikeysnail%2Freleases%2Flatest%2Fdownload%2Fikeysnail.box

from iOS Safari. Then JSBox will install iKeySnail.

You can also manually download the repository as a zip file and install it in JSBox.

Usage

See strings/settings.js for available shortcuts.

Customization

Edit strings/settings.js.

Defining / Customizing Keymap

We have four types of mode for key bindings.

1. all-mode, whose keymaps are always active.
   • https://github.com/mooz/jsbox-ksc/blob/master/strings/settings.js#L19
2. view-mode, whose keymaps are active only if the cursor isn't on editable elements (akin to vim's normal mode).
   • https://github.com/mooz/jsbox-ksc/blob/master/strings/settings.js#L81
3. rich-mode, whose keymaps are active only if the cursor is on rich text editors (such as CodeMirror, Ace, Scrapbox, and contenteditable).
   • https://github.com/mooz/jsbox-ksc/blob/master/strings/settings.js#L32
4. edit-mode, whose keymaps are active only if the cursor is on input or textarea.
   • https://github.com/mooz/jsbox-ksc/blob/master/strings/settings.js#L74

In each keymap, you can define a key's functionality in two ways:

1. Remapping to different key (e.g., "ctrl-s": "meta-f"), and
2. Invoke a JavaScript function (e.g., "ctrl-y": () => keysnail.paste()).
   • See keysnail object for checking available functionalities https://github.com/mooz/jsbox-ksc/blob/master/strings/content-script.js#L761

Defining a site

You can also define a site configuration in your settings.js. Configuration consists of

• keymap -> keymap
• style -> user css
• alias -> alias
• url -> url.

Examples are follows.

config.sites.push({
    alias: "Google",
    url: "https://www.google.com"
  });

  const GDOCS_KEYMAP = {
    rich: {
      "meta-f": keysnail.marked("alt-ArrowRight"),
      "meta-b": keysnail.marked("alt-ArrowLeft"),
      "meta-d": keysnail.marked("alt-Delete"),
      "ctrl-_": "ctrl-z",
      "ctrl-z": "meta-z",
      "ctrl-s": "ctrl-f"
    }
  };

  config.sites.push({
    alias: "Google Docs",
    url: "https://docs.google.com/",
    keymap: GDOCS_KEYMAP
  });

  config.sites.push({
    alias: "Google Docs (Slide)",
    url: "https://docs.google.com/presentation/",
    keymap: GDOCS_KEYMAP
  });

  config.sites.push({
    alias: "OverLeaf",
    url: "https://www.overleaf.com/project/",
    style: `
.toolbar { font-size: small !important; }
.entity { font-size: small !important; }
`
  });

  config.sites.push({
    alias: "Scrapbox",
    url: "https://scrapbox.io/",
    keymap: {
      rich: {
        "meta-f": keysnail.marked("alt-ArrowRight"),
        "meta-b": keysnail.marked("alt-ArrowLeft"),
        "ctrl-i": "ctrl-i",
        "ctrl-t": "ctrl-t"
      }
    },
    style: `
#editor {
  caret-color: transparent !important;
}
`
  });
