Indenting code in Sublime text 2?

You can find it in Edit → Line → Reindent, but it does not have a shortcut by default. You can add a shortcut by going to the menu Preferences → Keybindings → User, then add there:

{ "keys": ["f12"], "command": "reindent", "args": {"single_line": false} }  

(example of using the F12 key for that functionality)

The config files use JSON-syntax, so these curly braces have to be placed comma-separated in the square-brackets that are there by default. If you don't have any other key-bindings already, then your whole Keybindings → User file would look like this, of course:

[
    { "keys": ["f12"], "command": "reindent", "args": {"single_line": false}}
]

No one seems to love mac re-indentation, So here How I do it:

[
   { "keys": ["command+shift+i"], "command": "reindent"}
]

In Preferences > Key Binding - User

One more extra tip: add

{ "keys": ["command+0"], "command": "focus_side_bar" }

to have sidebar file tree view navigation using keyboard.

Note: Add , at the end of each {}, if you have more than one {} set of objects

There is no default shortcut for reindenting a file. However you can create one by following eznme's answer above.

You can also use the Command Palette by pressing:

1. Control+Shift+P (or ⌘+Shift+P on a Mac)
2. Type the first few characters of Reindent e.g: rein
3. Press Enter to run the command
   (The first command at the top should now show Indentation: Reindent Lines)

The reindent command only works on the currently selected lines unless the "single_line" argument is set to false.

{ "keys": ["f12"], "command": "reindent", "args": {"single_line": false} }

Now, pressing f12 will reindent the entire document.
