I would like to customize shortcut, but apply them only to a specific extension.
For example,
"jump to matching bracket" -> works in JS files -> customly bound to ctrl+m,
"go to matching tag pair" (emmet) -> works in HTML files -> I would like to ctrl+m also here, but doesn't work (ST3 understand "jump to matching bracket" which doesn't apply here).
I was wondering if specializing a shortcut to a specific extension would do the trick?
