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?
Apparently you can try something like this:
[
{ "keys": ["ctrl+x", "ctrl+i"],
"command": "insert_snippet",
"args": {"name": "Packages/User/mysnippet.sublime-snippet"},
"context": [ {"key": "selector", "operator": "equal", "operand": "text.tex.latex"} ]
}
]
Where you'ld replace the first 3 lines by what you want, and text.tex.latex by the scope you want (source.js and text.html.basic in your case).
