I'm hope you don't think I'm trying to be mean, it was just a really disappointing first experience. Might be my expectations were misaligned.
I had actually already installed the VSCode plugin and restarted both VSCode and Talon (I don't remember if I saw it in a comment in a .talon file, or if I saw it in the console logs, but somewhere it told me to install a plugin). Similarly, I installed the Rider/Idea.
I wasn't quite just saying anything :) Tho it wasn't clear what commands were actually accepted; from looking in the .talon files, I didn't see anything like a string literal, more something code-like. I had to guess at what commands were supported, for example "reload" in Chrome (assuming that's actually a correct command, even that simple command only worked some of the time).
I'm willing to give it another go, but is there a getting starting guide/tutorial for how to get started using it, and how to see what it's actually trying to do when it does something? I used the getting starting guide on the Talon site, but that only tells me how to install it, not actually how to use it.
