This can be helpful\n with some non-English keyboards (and can also be used to remap `Escape`).\n - For _Custom key mappings_ on the options page, lines which end with `\\` are now continued on the\n following line.\n- Process:\n - In order to provide faster bug fixes, we may in future push new releases without the noisy\n notification.\n\n- Post-release minor fixes:\n - 1.58.1 (2017-03-09) fix bug in `LinkHints.activateModeWithQueue` (#2445).\n - 1.58.2 (2017-03-19) fix key handling bug (#2453).\n\n1.57 (2016-10-01)\n\n- New commands:\n - `toggleMuteTab` - mute or unmute the current tab (default binding ``), see also\n [advanced usage](https://github.com/philc/vimium/wiki/Tips-and-Tricks#muting-tabs).\n- Other new features:\n - You can now map `` to a Vimium command (e.g. `map goBack`).\n - For link hints, when one hint marker is covered by another, `` now rotates the stacking\n order. If you use filtered hints, you'll need to use a modifier (e.g. ``).\n- Changes:\n - Global marks now search for an existing matching tab by prefix (rather than exact match). This\n allows global marks to be used as quick bookmarks on sites (like Facebook, Gmail, etc) where the\n URL changes as you navigate around.\n- Bug fixes:\n - `/i` can no longer hang Vimium while the page is loading.\n - `` is no longer handled (incorrectly) as `Escape`. This also affects ``.\n - If `goX` is mapped, then `go` no longer launches the vomnibar. This only affects three-key (or\n longer) bindings.\n\n1.56 (2016-06-11)\n\n- Vimium now works around a Chromium bug affecting users with non-standard keyboard layouts (see\n #2147).\n- Fixed a bug preventing visual line mode (`V`) from working.\n\n1.55 (2016-05-26)\n\n- New commands:\n - `visitPreviousTab` - visit the previous tab (by recency) with `^`, or the tab before that with\n `2^`.\n - `passNextKey` - pass the next key to the page. For example, using `map passNextKey`, you\n can close Facebook's messenger popups with ``.\n- Link hints:\n - Now work across all frames in the tab.\n - Now select frames and scrollable elements.\n - Now accept a count prefix; `3F` opens three new background tabs, `999F` opens many tabs.\n - For filtered link hints, a new option on the settings page requires you to press `Enter` to\n activate a link; this prevents unintentionally triggering Vimium commands with trailing\n keystrokes.\n- Miscellaneous:\n - `gg` now accepts a `count` prefix.\n - `W` now accepts a count prefix; `3W` moves three tabs to a new window.\n - With smooth scrolling, `2j`-and-hold now gives a faster scroll than `j`-and-hold.\n - You can now bind keys to a command with a defined count prefix; for example,\n `map d scrollDown count=4`.\n - You can now bind three-key (or longer) sequences; for example, `map abc enterInsertMode`.\n - `c-y` and `c-e` now scroll in visual mode.\n - The Vimium help dialog has been re-styled.\n- Bug fixes:\n - `` is no longer treated as escape.\n - Fix icon display and memory leak due to a regression in recent Chrome versions (49+).\n- For web-devs only:\n - When disabled on a tab, Vimium no longer pollutes the dev console with network requests.\n\n1.54 (2016-01-30)\n\n- Fix occasional endless scrolling (#1911).\n\n1.53 (2015-09-25)\n\n- Vimium now works on the new-tab page for Chrome 47.\n- `g0` and `g$` now accept count prefixes; so `2g0` selects the second tab, and so on.\n- Bug fixes:\n - Fix `moveTabLeft` and `moveTabRight` for pinned tabs (#1814 and #1815).\n\n1.52 (2015-09-09)\n\n- Search completion for selected custom search engines (details on the\n [wiki](https://github.com/philc/vimium/wiki/Search-Completion)).\n- Use `Tab` on an empty Vomnibar to repeat or edit recent queries (details on the\n [wiki](https://github.com/philc/vimium/wiki/Tips-and-Tricks#repeat-recent-vomnibar-queries)).\n- Marks:\n - Use \\`\\` to jump back to the previous position after jump-like movements:
(`gg`,\n `G`, `n`, `N`, `/` and local mark movements).\n - Global marks are now persistent and synced.\n- For numeric link hints, you can now use `Tab` and `Enter` to select hints, and hints are ordered\n by the best match.\n- The Find Mode text entry box now supports editing, pasting, and better handles non-latin\n characters.\n- Vimium now works on XML pages.\n- Bug fixes.\n\n1.51 (2015-05-02)\n\n- Bug\n [fixes](https://github.com/philc/vimium/pulls?utf8=%E2%9C%93&q=is%3Apr+sort%3Aupdated-desc+is%3Aclosed+merged%3A%3E%3D2015-04-26+merged%3A%3C2015-05-02+state%3Amerged).\n\n1.50 (2015-04-26)\n\n- Visual mode (in beta): use `v` and then vim-like keystrokes to select text on the page.

Great! Before getting started, understand Vimium's\ndesign principles and the goals of the maintainers.\n\n### Vimium design principles\n\nWhen people first start using Vimium, it provides an incredibly powerful workflow improvement and it\nmakes them feel awesome. Surprisingly, Vimium is applicable to a huge, broad population of people,\nnot just users of Vim.\n\nIn addition to power, a secondary goal of Vimium is approachability: minimizing the barriers which\nprevent a new user from feeling awesome. Many of Vimium's users haven't used Vim before -- about 1\nin 5 Chrome Store reviews say this -- and most people have strong web browsing habits forged from\nyears of browsing. Given that, it's a great experience when Vimium feels like a natural addition to\nChrome which augments, but doesn't break, the user's current browsing habits.\n\n**Principles:**\n\n1. **Easy to understand**. Even if you're not very familiar with Vim. The Vimium video shows you all\n you need to know to start using Vimium and feel awesome.\n2. **Reliable**. The core feature set works on most sites on the web.\n3. **Immediately useful**. Vimium doesn't require any configuration or doc-reading before it's\n useful. Just watch the video or hit `?`. You can transition into using Vimium piecemeal; you\n don't need to jump in whole-hog from the start.\n4. **Feels native**. Vimium doesn't drastically change the way Chrome looks or behaves.\n5. **Simple**. The core feature set isn't overwhelming. This principle is particularly vulnerable as\n we add to Vimium, so it requires our active effort to maintain this simplicity.\n6. **Code simplicity**. Developers find the Vimium codebase relatively simple and easy to jump into.\n This allows more people to fix bugs and implement features.\n\n### Which pull requests get merged?\n\n**Goals of the maintainers**\n\nThe maintainers of Vimium have limited bandwidth, which influences which PRs we can review and\nmerge.\n\nOur goals are generally to keep Vimium small, maintainable, and really nail the broad appeal use\ncases. This is in contrast to adding and maintaining an increasing number of complex or niche\nfeatures. We recommend those live in forked repos rather than the mainline Vimium repo.\n\nPRs we'll likely merge:\n\n- Reflect all of the Vimium design principles.\n- Are useful for lots of Vimium users.\n- Have simple implementations (straightforward code, few lines of code).\n\nPRs we likely won't:\n\n- Violate one or more of our design principles.\n- Are niche.\n- Have complex implementations -- more code than they're worth.\n\nTips for preparing a PR:\n\n- If you want to check with us first before implementing something big, open an issue proposing the\n idea. You'll get feedback from the maintainers as to whether it's something we'll likely merge.\n- Try to keep PRs around 50 LOC or less. Bigger PRs create inertia for review.\n\nHere's the rationale behind this policy:\n\n- Vimium is a volunteer effort. To make it possible to keep the project up-to-date as the web and\n browsers evolve, the codebase has to remain small and maintainable.\n- If the maintainers don't use a feature, and most other users don't, then the feature will likely\n get neglected.\n- Every feature, particularly neglected ones, increase the complexity of the codebase and makes it\n more difficult and less pleasant to work on.\n- Adding a new feature is only part of the work. Once it's added, a feature must be maintained\n forever.\n- Vimium is a project which suffers from the\n [stadium model of open source](https://github.com/philc/book-notes/blob/master/engineering/working%20in%20public%20-%20nadia%20eghbal.md#the-structure-of-an-open-source-project-chap-2):\n there are many users but unfortunately few maintainers. As a result, there is bandwidth to\n maintain only a limited number of features in the main repo.\n\n### Installing From Source\n\nVimium is written in Javascript. To install Vimium from source:\n\n**On Chrome/Chromium:**\n\n1. Navigate to `chrome://extensions`\n1. Toggle into Developer Mode\n1. Click on \"Load Unpacked Extension...\"\n1. Select the Vimium directory you've cloned from Github.\n\n**On Firefox:**\n\nFirefox needs a modified version of the manifest.json that's used for Chrome. To generate this, run\n\n`./make.js write-firefox-manifest`\n\nAfter that:\n\n1. Open Firefox\n1. Enter \"about:debugging\" in the URL bar\n1. Click \"This Firefox\" on the left side\n1. Click \"Load Temporary Add-on\"\n1. Open the Vimium directory you've cloned from Github, and select any file inside.\n\n### Running the tests\n\nOur tests use [shoulda.js](https://github.com/philc/shoulda.js) and\n[Puppeteer](https://github.com/puppeteer/puppeteer). To run the tests:\n\n1. Install [Deno](https://deno.land/) if you don't have it already.\n2. `deno run -A npm:puppeteer browsers install chrome` to install puppeteer\n3. `./make.js test` to build the code and run the tests.\n\n### Coding Style\n\n- Run `deno fmt` at the root of the Vimium project to format your code.\n- We generally follow the recommendations from the\n [Airbnb Javascript style guide](https://github.com/airbnb/javascript).\n- We wrap lines at 100 characters.\n- When writing comments, uppercase the first letter of your sentence, and put a period at the end.\n- We're currently using JavaScript language features from ES2018 or earlier. If we desire to use\n something introduced in a later version of JavaScript, we need to remember to update the minimum\n Chrome and Firefox versions required.\n" }, { "path": "CREDITS", "content": "Authors & Maintainers:\n Ilya Sukhar (github: ilya)\n Phil Crosby (github: philc)\n\nContributors:\n acrollet\n Adam Lindberg (github: eproxus)\n akhilman\n Ângelo Otávio Nuffer Nunes (github: angelonuffer)\n Bernardo B.

Overrides Chrome's default behavior for that\n key, if any.\n- `unmap key`: Unmaps a key and restores Chrome's default behavior (if any).\n- `unmapAll`: Unmaps all bindings. This is useful if you want to completely wipe Vimium's defaults\n and start from scratch with your own setup.\n\nExamples:\n\n- `map scrollPageDown` maps ctrl+d to scrolling the page down. Chrome's default behavior of\n showing a bookmark dialog is suppressed.\n- `map r reload hard` maps the r key to reloading the page, and also includes the \"hard\" option to\n hard-reload the page.\n- `unmap ` removes any mapping for ctrl+d and restores Chrome's default behavior.\n- `unmap r` removes any mapping for the r key.\n\nSee the [docs](https://vimium.github.io/commands/) for every Vimium command and its options.\n\nYou can add comments to key mappings by starting a line with `\"` or `#`.\n\nThe following special keys are available for mapping:\n\n- ``, ``, ``, `` for ctrl, alt, shift, and meta (command on Mac) respectively\n with any key.
