You can edit the default ones by editing the files that generate them inside of your Packages directory. Just browse through the folders to the specific language or check the Default folder to find the right file to edit for one of the defaults.

You can create custom snippets as well as modify the default ones by going to Preferences > Browse Packages > User and creating a new file with the .sublime-snippet extension.

Then inside the file paste the following:

<snippet>
    <content><![CDATA[Type your snippet here]]></content>
    <!-- Optional: Tab trigger to activate the snippet -->
    <tabTrigger>xyzzy</tabTrigger>
    <!-- Optional: Scope the tab trigger will be active in -->
    <scope>source.python</scope>
    <!-- Optional: Description to show in the menu -->
    <description>My Fancy Snippet</description>
</snippet>

Alternatively, you can go to Tools > New Snippet and it will open the snippet template in a new file that you can then save and name with the same extension as above.

Another option, is this way using the Gist package. The only thing I don't like about this setup is it creates a new file with the snippet rather than pasting it into your current file at your cursor. Still it is good for coordinating your most used snippets across several computers.

Answer 2

I believe you're looking to customize the snippets.

Go to Preferences --> Browse Packages --> C++ and make whatever changes you need :)
