I'm clearly a big fan of Keyboard Maestro. I've known about its built-in web server for a while, but never had a good reason to use it, despite having spent some time considering the possibilities. (And I'm not unfamiliar with remote control over the HTTP, having used X2Web for home automation quite a bit.)
But the other day it suddenly dawned on me; it's a simple way to solve a frequent inconvenience. You see, I live and work in a loft. This means that my computer is basically in my living room, dining room, kitchen, and so on. This is a benefit when I'm waiting for an incoming chat message, or email, or FaceTime call. I can hear the ring tone no matter where I am. But when I'm not expecting an important missive, it's a drag hearing the other beeps and bongs that go off for various reasons. I'm not mindful enough to mute the computer when I walk away, so I inevitably end up having to dash back and silence it when it starting making noise at an inopportune time.
But now that problem is solved. I created a very simple macro that toggles the mute setting. I then turned on web access for that macro, and of course turned on Keyboard Maestro's web server. Now, from any other computer, iPhone, or iPad in the house, I can trigger the macro without walking a step. Ahhh, sweet, sweet silence.
