Developer TODO (don't remove)

• update documentation
  Add native screen recorder activity.

is this an action?

[githubsterer]

Yes, sorry. An action.

[jambl3r]

No good API to do that.
Key Mapper would have to implement its own screen recording module which doesn't feel appropriate.
Potentially toggling a quick settings tile if your OS has implemented its own screen recorder or sending an intent to a third party one may do what you want
