@jr5 No argument. You can certainly trigger any sort of action in multiple different ways - keyboard shortcut, StreamDeck button, custom workflow in Alfred (or any of the similar “butler” apps), gesture on the trackpad (via BTT or KM, for example).
Notice that I did not mention Shortcuts. I am still a novice with Shortcuts, so few of my workflows originate there, but there are a few things that I have only been able to accomplish with Shortcuts, and since KM and BTT can launch a shortcut …
I have tendency to create a workflow in the app that I think will be the most convenient for what I am trying to accomplish, most commonly either a KM macro or an Alfred workflow, and then link that workflow into the various other apps with their ability to run scripts or other triggers.
The result is that many of my most commonly used workflows can be launched in multiple different ways, but all of those launch mechanisms will funnel into one implementation.
Sometimes it’s easier to use the SD. For example, when in Mail, as I go through messages I often want to mark one or more as read and then delete them, which I can do with a button on SD or via a conflict palette in KM that includes various macros active only in Mail. The KM approach is two keystrokes (launch the palette with META-A then hit the “D” key to invoke the read and delete macro), but the SD requires one button press. For email that I want to archive, there is another button (and entry in the conflict palette) that takes care of that (marks the email read and saves it to the proper place on my Synology).
If I am at my desk, I tend to mouse with my right hand and click buttons with my left. However, when on my MBAir, I tend to “mouse” the trackpad with my right hand and use the keyboard with my left (which is why META-A is the key sequence most commonly used: It’s easy to launch the conflict menu quickly and I generally keep the key press needed to invoke a macro from that menu on the left hand side of the keyboard so it remains a one-handed operation(.
You may find it better / easier to just launch everything from the keyboard. That’s the beauty of this: the ability to customize so thoroughly means that we can each find what works best for us and make it happen.
