* Get the next key from keyMap

* Keys can be referenced by `{key}` or `{special}` as well as physical locations per `[code]`.
* Everything else will be interpreted as a typed character - e.g. `a`.
* Brackets `{` and `[` can be escaped by doubling - e.g. `foo[[bar` translates to `foo[bar`.
* Keeping the key pressed can be written as `{key>}`.
* When keeping the key pressed you can choose how long (how many keydown and keypress) the key is pressed `{key>3}`.
* You can then release the key per `{key>3/}` or keep it pressed and continue with the next key.
* Modifiers like `{shift}` imply being kept pressed. This can be turned of per `{shift/}`.
