To record a macro, simply press Ctrl + Q on Windows or Linux and Control + Q on OS X. We will notice that the status bar says Starting to record macro…, as shown in the following screenshot:

Let's record the macro. Press Ctrl + right arrow + ; + Enter on Windows or Linux and Command + Right Arrow + ; + Return on OS X. Finally, press Ctrl + Q to stop recording.

To play the recorded macro, simply press Ctrl + Shift + Q on Windows or Linux and Control + Shift + Q on OS X. Sublime will always play the last recorded macro.

We can also save the recorded macro and edit it manually. Let's go to Tools | Save Macro… and save it under Packages/User/semicolon.sublime-macro. When opened open it for editing, we should see the following:

[
   { "args": { "to": "eol" }, "command": "move_to" },
   { "args": { "characters": ";" }, "command": "insert" },
   { "args": { "characters": "
" }, "command": "insert" }
]

We can edit the macro to insert); instead of ; just by changing the value of "characters" in the second row to ");".

We recorded, saved, and edited our macro. Now, we want to make it accessible for later use, and one way of doing this is by binding the macro to a shortcut key. We will do this by defining a new key binding to our macro.
