When I press Ctrl + E in my ST3,it appears like this;

(the ^ mean the cursor position）

As I know , the default biding’s command means “slurp_find_string” which can be find in default(windows).sublime-keymap.

How can I find a key binding was set at which keymap file of which package ?

I’m pretty sure that is emmet.

But you can find key conflicts with this package: github.com/skuroda/FindKeyConflicts

use this:
sublime.wbond.net/packages/FindKeyConflicts

Yes, you are right.

I have open the folder Sublime Text Build 3047 x64\Data\Packages by ST, and search Ctrl+E by Find in folder….

I find the keybinding of Emmet.

I have disabled it by setting it’s command as null in Key Bindings - User.

Thanks for your solution!

Actually it’s enough to add “enable_emmet_keymap”: false in your config file.
