how to set ctrl+[ instead of escape in sublime text 3?

Question

I use vim mode in sublime text 3, I want to use ctrl+[ instead of esc.

This is my keymap config:

[
    // vim_mode
    // exit insert mode, same to 'esc'
    { "keys": ["ctrl+["], 
        "command":

    },
    {
        // auto_complete
        // use tab to backward to prev completion source
        "keys": ["ctrl+p"],
        "command": "move",
        "args": { "by": "lines", "forward": false },
        "context":
        [
            { "key": "auto_complete_visible" },
        ],
    },
]

after I map all escape commands and vim exit insert mode to ctrl+[, when I type this:

the ctrl+[ doesn't work, the selection will not disappear until I press the esc.

why ctrl+[ cannot make it disappear ?

You can create a single command to exit to a clean command mode by installing ChainOfCommand (or creating a macro) and just call all "exit" commands at once. Just install it and paste this into your keymap:

{
    "keys": ["ctrl+["],
    "command": "chain",
    "args": {
        "commands": [
            ["hide_overlay"],
            ["hide_popup"],
            ["hide_auto_complete"],
            ["hide_panel", {"cancel": true}],
            ["clear_fields"],
            ["single_selection"],
            ["exit_insert_mode"],
            ["exit_visual_mode"],
        ]
    },
},
