MacOS – Disable Cmd + , in Safari

keyboardmacossafarishortcut

I'm currently doing a lot of chemistry writing in Google Docs. Google Docs is great for it because Cmd+. formats as superscript and Cmd+, formats as subscript… both of which supersaturate chemical writings (fear not, that's my only pun). Superscript works great, but Safari has an overriding Cmd+, which brings up Preferences-General and highlights Homepage, so subscript doesn't work. I haven't yet found a way to disable Safari's particular shortcuts, so I'm hoping someone here does.

in short:

  1. Edit ~/Library/Preferences/com.apple.symbolichotkeys.plist (you can use Xcode).
  2. Find the code for kCGHotKeyLookUpWordInDictionary (70), and set 'enabled' to OFF (if it's not there just create an entry '70' with 'enabled' = OFF).
  3. Restart your system

EDIT: In your case, it should be:

Key Down
    Characters: ,
    Unicode:        44 / 0x2c
    Keys:       ⌘,
    Key Code:   43 / 0x2b
    Modifiers:  1048848 / 0x100110

so you should be using key code 43 with modifier 1048848
