When in a browser (Chrome or Safari), the following keyboard shortcut will always bring up a window that says "Welcome To Mail":
I would like to use this shortcut for another purpose. Is there any way to disable this shortcut?
You can change the shortcuts from System Preferences:
If you want to disable the shortcuts, edit the NSUserKeyEquivalents dictionaries directly:
defaults write com.google.Chrome NSUserKeyEquivalents -dict-add 'Email Page Location' '\0' defaults write com.google.Chrome.canary NSUserKeyEquivalents -dict-add 'Email Page Location' '\0' defaults write com.apple.Safari NSUserKeyEquivalents -dict-add 'Email Link to This Page' '\0' 'Email This Page' '\0'
Then quit and reopen Chrome and Safari to apply the changes.
Taking a look at Chrome's keyboard shortcuts helps.
Cmnd+Shift+I is to "Email the current page". It's a bit annoying because it's so close to the developer tools (Cmnd+Opt+I).
The command-line solution given in another answer eventually worked for me but I needed to do one more thing:
defaults write com.google.Chrome NSUserKeyEquivalents -dict-add 'Email Page Location' '\0',
I entered the command:
killall cfprefsd (and
killall Finder for good measure).
This stopped the annoying Cmd-Shift-I shortcut on Chrome from creating a new mail message, but I can't get it to stop happening in Safari, unfortunately.
killall cfprefsd clears the preferences cache
killall Finder restarts the Finder
The GUI method described at the top didn't work at all for me, but maybe because I didn't clear the prefs cache.
The accepted answer is not working on my MacBook Pro with macOS Sierra system.
I found a solution to disable Command+Shift+i in Chrome:
Install the Chrome extension Shortkeys.
Open the Shortkeys's preference panel, add a
command+shift+i shortcut like below:
Now you can say goodbye to the annoying Mac Mail!
Unfortunately none of the answers given here were able to prevent Command+I from triggering Email This Page in Safari for me (running macOS Sierra). The only way I have been able to prevent that behavior is by using FastScripts to map Command+I to an empty AppleScript. The script must be stored in
~/Library/Scripts/Applications/Safari to prevent it from disabling use of the shortcut for italics in other applications.
Unfortunately this approach has the side effect of disabling the use of Command+I to toggle italics in Safari where that is its default behavior, such as in Google Docs or in this answer box on AskDifferent. For me that's worth avoiding being thrown into my email inbox whenever I try to italicize text in a text box in Safari that doesn't support it.
You can also use Better Touch Tool to override the shortcuts (globally or for any specific application).
Given I was already using this app, it's been the solution for me since none of the other answers mentioned here worked for me (High Sierra), and I didn't want to install new software.
Easiest way which i could find is assign this shortcut to any of install extension
