[Slack] has a couple of useful keyboard shortcuts for navigating between unread channels. Unfortunately they use awkward combinations of keys involving multiple modifiers and an arrow key (<span class="keyboard-shortcut">⌥⇧↓</span> and <span class="keyboard-shortcut">⌥⇧↑</span>). If these shortcuts were exposed in the menu bar they could be modified using the [built-in support for custom shortcuts in Mac OS X][custom-shortcuts]. As an alternative the following [Karabiner] config can be used to change the next unread shortcut to something more sane. I chose <span class="keyboard-shortcut">⌘J</span>: [Slack]: https://slack.com/ [Karabiner]: https://pqrs.org/osx/karabiner/ [custom-shortcuts]: https://support.apple.com/kb/PH18418 <script src="https://gist.github.com/wezm/05210d76660e735944a7.js"></script> [View Code][code] [code]: https://gist.github.com/wezm/05210d76660e735944a7
