How to set a keyboard shortcut for converting from tabs to spaces in sublimetext2

Question

What is the option in the Key Bindings file that I would use to set up a keyboard shortcut for the menu item

View -> Indentation -> Convert Indentation To Spaces

I've tried the following, but can't figure out how to trigger the option I see in the above mentioned menu

{ "keys": ["super+t"], "command": "convert_to_tabs" },
{ "keys": ["shift+super+t"], "command": "convert_to_spaces" },

Answer 1

Simple Version

Convert spaces to tabs (from Eric Muyser):

{ "keys": ["ctrl+shift+x"], "command": "unexpand_tabs", "args": { "set_translate_tabs": false } }

Convert tabs to spaces (from mVChr):

{ "keys": ["ctrl+shift+y"], "command": "expand_tabs", "args": { "set_translate_tabs": true } }

You could do it with one command each (expand_tabs and unexpand_tabs), but it would also be a good idea to toggle "Indent Using Spaces". Here is a macro that I saw somewhere (I forget where.)

Macro Version

Tabs -> Spaces

Save as "convert_tabs_to_spaces.sublime-macro" inside of your "Packages/User" folder

[
  {
    "args":
    {
      "set_translate_tabs": true
    },
    "command": "expand_tabs"
  }
]

Add this to your keybindings file:

    { "keys": ["ctrl+shift+x"], "command": "run_macro_file", "args": {"file": "Packages/User/convert_tabs_to_spaces.sublime-macro"} },

Spaces -> Tabs

Similar file name and keybinding

[
  {
    "args":
    {
      "set_translate_tabs": false
    },
    "command": "unexpand_tabs"
  }
]

I used this until I saw that you could left click the indentation setting in the Status Bar and change it from there.

Edit:

Plugin Version

adapted from here

"convert_tabs_to_spaces.py"

import sublime, sublime_plugin

class ConvertTabsToSpaces(sublime_plugin.TextCommand):
    def run(self, edit):
        self.view.run_command('expand_tabs', {"set_translate_tabs": True})

.

keybinding: { "keys": ["ctrl+shift+x"], "command": "convert_tabs_to_spaces"},

"convert_spaces_to_tabs.py"

import sublime, sublime_plugin

class ConvertSpacesToTabs(sublime_plugin.TextCommand):
    def run(self, edit):
        self.view.run_command('unexpand_tabs', {"set_translate_tabs": False})

.

keybinding: { "keys": ["ctrl+shift+y"], "command": "convert_spaces_to_tabs"},
