Mail.app - Shortcut to switch signatures?

Sorry to dig up an old question, but I had the identical issue today and this was the first result for my google search for “mac mail signature shortcut”. While these answers weren’t what I was looking for, the 3rd google result was a MacWorld hint, which offered the perfect solution.

Here’s the answer: you can assign keyboard shortcuts for your email signatures, “From:” account selection, and even SMTP account from System Preferences → Keyboard → Keyboard Shortcuts → Application Shortcuts. To set up your shortcut, click the + icon, select “Mail.app” from the Application drop down, enter the text of the signature (or other option) as it appears in the New Message window drop down, and give it a keyboard shortcut. Rob Griffiths, the author of the MacWorld hint, advises using (control) in combination with your desired keys to avoid conflicts with existing Mail shortcuts, which seems smart.

In my case, I created a shortcut in Mail.app for the menu title “None” (the first option under signatures) and assigned it the shortcut ⌃X. It is now exceedingly easy for me to clear my default email signature when it doesn’t seem appropriate.

For the purposes of illustration, here is the System Preferences → Keyboard Shortcuts pane (it’s the last item): Screenshot of System Preferences → Keyboard Shortcuts pane

And here is what it looks like in Mail’s New Message window: Screenshot of Mail’s New Message window


In "System Preferences", go to "Language & Text." Under the "Text" button, you have "Symbol & Text Substitution." You should be able to setup a substitution there.

Having said that, I use TextExpander, which is also a paid app ($35). I find it to be very worthwhile.
