2. Switching apps • Happens fairly often for most people. • Generally unavoidable.
3. Command/Alt-Tab • Works okay when you only deal with two apps. • Cognitive effort: • Need to figure out how many tabs to get to the app you want.
4. Solution • Global keyboard shortcuts for each app you frequently use. • Text editor/IDE, browser, terminal, Skype, Twitter, iTunes, Messages/iChat, Adium, Sparrow/Mail, etc. • Ideally accessible with left hand so right hand can mouse if needed. • Pick a prefix: Cmd+Shift, Cmd+Ctrl (via Caps Lock), etc. • Apps that do it: Alfred, Quicksilver. • Bonus: Launch apps with keyboard shortcuts.
7. Arrow Keys • Long way from home row • Commonly used • Except maybe for vim users • Can’t avoid it in the OS... or so you may think.
8. Solution • Rebind them everywhere! • People bind Caps Lock to be Control already. • Two options: • KeyBindingsEditor • KeyRemap4Macbook
9. KeyBindingsEditor • http://www.cocoabits.com/ KeyBindingsEditor/ • GUI Editor for ~/Library/ DefaultKeyBinding.dict • Applies to all Cocoa NSTextFields unless they have been overridden.
11. Keyremap4Macbook • http://pqrs.org/macosx/ keyremap4macbook/ • Apps still sees arrow keys when you rebind (most of the time) • Installs its own keyboard driver (potentially risky).
13. Backtraces in Terminal • Usual workflow: • Get a backtrace either from spec or whatever • Either copy the path or manually type into editor. • Pain in the ass.
14. Solution • iTerm2’s Semantic History • Cmd+Click on backtrace to open it in editor. • Bonus: Cmd+Drag to get a file handle • Video: http://vimeo.com/21872771
16. Demonstration
17. Get a file path into the terminal • e.g., get current open file in editor into terminal to run a test/commit/whatever. • Most people type path in with lots of <Tab> mashing • Some people drag file handle from titlebar.
18. Solution • filepath • small CLI utility that simply prints the path of the most recently active document (title bar icon thing). • http://github.com/chendo/filepath • Alias to ‘fp’ for bonus points. • Example usage: rspec `fp`
19. Gestures • Magic Trackpad / Macbooks • Ever wanted to customise gestures?
20. Solution • BetterTouchTool • http://blog.boastr.net/?page_id=1722 • Bind gestures to keyboard shortcuts, window actions, system actions. • Adds a shitload more gestures to use.
22. Key repeat speed • Mostly used for arrow keys and backspace. • Or in anger. • Should be at max.
23. Want even faster key repeat?
24. Rebind Caps Lock • You should be doing it already.
25. The Problem with Shortcuts
26. The problem with shortcuts • Remembering them is hard • Many things don’t have shortcuts • Much easier to use the mouse, even though it means taking hands off the keyboard
27. Idea • What if you could use the keyboard for where you would normally mouse? • Minimise the time between deciding an action and performing the action • Quicksilver/Alfred/LaunchBar for UI elements • Completely keyboard-driven
28. Shortcat
29. Shortcat • Quicksilver/Alfred/Launchbar/Spotlight for UI elements • Works everywhere that exposes Accessibility API. Including Safari! • The aim is to kill mousing.
30. Useful for • Keyboard warriors • People unable to/find it difficult to use a mouse • Vision-impaired • Mountain Lion Dictation AKA lazy
31. Internals • MacRuby • Accessibility API • CoreAnimation
32. Halp • Very new to Cocoa • Not sure how to test • CoreAnimation • Global keyboard event tapping
