Hammerspoon

This configuration provide a lot of hotkeys for productivity without change established habits.

Install

• $ brew cask install hammerspoon
• $ git clone https://github.com/cxdongjack/hammerspoon.git ~/.hammerspoon

Improve window hints

Make the window hints to fixed hotkey

Hotkey generation algorithm as below:

• try to find char in user specific dict, like { ['com.sublimetext.3'] = 'S' }
• parse the bundleID to single char, like com.apple.Terminal -> 'T', bundleID is stable than title
• loop the charhints(i.e ABC..XYZ), find the nil char in 'dict'

Emacs style hotkeys

This configuration heavily uses Emacs style hotkey binding, i.e., using the prefix to activate hotkeys. The default prefix is ctrl+,, e.g., prefix - w = press and release ctrl+, first, then press w.

• prefix - ?: help.
• prefix - g: show a 3x3 grid for resizing window.
• prefix - w: switcher for windows(while system switcher for application).
• prefix - c: toggle caffeinate (disable sleep).
• prefix - s: sleep.
• prefix - n: toggle night shift.
• prefix - r: reload Hammerspoon config.
• prefix - d: toggle Hammerspoon console for debug.
• prefix - m: enter mouse mode, then you can use hjkl to move the mouse, use cmd+hjkl to move slowly, use shift+hjkl to scroll, use u, i, o to perform left, right, middle button click.

Normal Keymaps

The option key is used for inputing special characters, may mapping option key be a better offer.

• option [ + shift ] + tab: switch windows.
• option + npfb: arrow keys.
• option + ctrl + npfb: option + arrow keys (move faster).
• option + a: home.
• option + e: end.
• option + u: page_up.
• option + d: page_down.
• option + [/]: cmd [+ shift] + tab (switch tabs).
• option + q: esc.
• option + m / option + 1: play.
• option + < / option + 2: previous track.
• option + > / option + 3: next track.
• option + / / option + f1: mute.
• option + , / option + f2: volume down.
• option + . / option + f3: volume up.
• press ctrl twice: escape
• press cmd Q twice: quit app, in order to prevent accidentally quitting an app when pressing cmd+q.
