How to shorten list of syntax options in Sublime Text

Solution 1:

You can disable a lot of syntaxes by disabling it's package with Package Control.

• Ctrl + shift + P
• type disable, and select "Package Control: Disable Package"
• Find syntax's package and select it.

Solution 2:

Using @d_rail's advice, I disabled the packages. That resulted in the following settings in my User preferences file:

{
    "ignored_packages":
    [
        "ActionScript",
        "C++",
        "Haskell",
        "TCL",
        "Go",
        "Lisp",
        "Graphviz",
        "Scala",
        "Pascal",
        "Clojure",
        "ASP",
        "Vintage",
        "Objective-C",
        "R",
        "RestructuredText",
        "Erlang",
        "Groovy",
        "Lua",
        "OCaml",
        "C#",
        "Matlab",
        "Textile",
        "D",
        "Batch File",
        "AppleScript",
        "Makefile",
        "LaTeX",
        "Java"
    ]
}
