Hotkey to end the line with a semicolon and jump to a new line in Sublime Text 2

Best solution for this is recording a macro on Sublime Text and then assigning it to a keyboard shortcut. Follow these steps:

1. Create a line such as alert(‘hello’) and leave the cursor right
   after letter ‘o’.
2. Then go to Tools > Record a Macro to start recording.
3. Press Command+→ to go to the end of line.
4. Press ; and hit Enter
5. Stop recording the macro by going to Tools > Stop Recording Macro
6. You can now test your macro by Tools > Playback Macro (optional)
7. Save your macro by going to Tools > Save Macro (ex: EndOfLine.sublime-macro)

8. Create a shortcut by adding this between the square brackets in your
   in your Preferences > Key Bindings – User file:

   {
   "keys": ["super+;"], "command": "run_macro_file", "args": {"file": "Packages/User/EndOfLine.sublime-macro"}
   }
   

9. Now, every time you hit Command+;, it will
   magically place the semicolon at the end of current line and move the cursor to the next line.

Happy coding!
