If you'd like to take a crack at setting up some Mac automations without spending the money that Keyboard Maestro ($36) or Better Touch Tool ($24) will run you, then you should download and try Keyboard Cowboy, a free and open-source automation tool available from the dev's Github site. It doesn't come close to having all of the features of the more advanced apps, but it has plenty of functionality, nonetheless.
Thereβs nothing like one too many automation tools.
