The plugin mentioned is an evolution of a select to character command originally written for ST1. It highlighted the character regions to provide some predictability. I was `playing` about after that with some weird bisecting navigation, using a skip jump, reverse and skip again style, made possible because of the predictability. Then I thought about just using [di]graphs (and later non contiguous digraphs) I called it hotspots.
@COD312 asked about EasyMotion and it sounded like my old plugin. From what I've read/heard of EasyMotion I don't think you could currently implement it in Sublime. I wish you could as I think it's a superior method. It does a similar menuising of the visible region but [a]nstead [b]t [c]aints [d]etters [e]ver [f]he [g]okens. Reading that, you'd imagine it wouldn't be that practical, but consider you are already laser targeted on where you want to go typically when you initiate a motion.
@COD312 was recently asking me about publishing the plugin. Maybe I will. Just don't expect EasyMotion. It's similar in scope but different in execution.
It is better to remain silent and be thought a fool, than to speak out and remove all doubt
