How to remap my Backspace to a 'd' while in Visual Mode with Vintage in Sublime

While in visual mode with if you highlight some text and press backspace the cursor will continue to move back and continue to highlight more of your code; however, if you hit the d key, the highlighted text will be deleted and sublime will move back into command mode.

I'd like my backspace key to be mapped to my d key but only when I'm in visual mode. But I think that it's more like I'd like to map my backspace key to the same command as my d key when I'm in visual mode (because I think that's how sublime goes about emulating vim anyways, but not completely sure) How would I go about doing this? Thanks for your help :)

Solution

Try this one

{ "keys": ["backspace"], "command": "set_action", "args": {
    "action": "vi_delete",
    "description": "Delete"},
    "context": [{"key": "setting.command_mode"}]
},
