Place file in your User folder
On Mac it is:
/Users/username/Library/Application Support/Sublime Text 2

---
Here are 3 methods for popping up Sublime Text's quick_panel

1 -- How to run this from console-----------------------------------
Once installed, run the following command from
the Python console (Ctrl+`):

view.run_command("insert_date_panel")
and you will see the list in the quick panel

Press Esc to cancel,
be careful if you run this when this file
is viewed, it will add the date text to this file. Try it on
a new blank file.


2 -- How to add this to a hotkey------------------------------------
How to add this to the hotkey ctrl+shift+8
by:
adding
{ "keys": ["ctrl+shift+8"], "command": "insert_date_panel" }
this to file
/Users/myusernameonmac/Library/Application Support/
    Sublime Text 2/Packages/User/Default (OSX).sublime-keymap

Note:
    You must use
    "insert_date_panel"
    for the class
    InsertDatePanelCommand
      i.e. CamelCase must be converted to lower case, with underscores

3 -- How to add this to the Command Palette  (Cmd-Shift-P) on Mac ---

a- Create a file:
  /Users/robmccormack/Library/Application Support/Sublime Text 2/
     Packages/User/Default.sublime-commands

  There is same file type of file located in:
      Packages/Default/Default.sublime-commands

   don't modify files in Packages/Default,
   they will be overwritten when upgrading
   always use the /User
   folder for user specific settings.

b- add this to file:
    Default.sublime-commands
[
     {
        "caption": "Insert Date from Quick Panel",
        "command": "insert_date_panel"
    }
]


c- Then you can press Cmd-Shift_P, and type in:
   Inser...
   - the first few letters of:
       Insert Date from Quick Panel
   and you will see this on list
