How to batch keystrokes together

[nikitavoloboev]

It's not clear how I can batch multiple keystrokes together in the action.

I want to make a binding on b key to insert TODO:. With a space after.

I would think I'd have to do something like this [:b [:T][:O]] to achieve this but not sure. The tutorial is not clear about it either.

it's [:b [:!St :!So :!Sd :!So]].
