Feature idea: subscribing to key events when focus on edit fields
When the edit fields (above each marker) are focused, pressing up to increment or down to decrement would be nice :) (Not just keyup, because being able to hold them down watch it expand/shrink would be nice)
The idea is interesting, but I'm just wondering how user will know they can use arrows on their keyboards to increase/decrease selected value.
They don't need to necessarily know. There's already an obvious way to manipulate it but it's a nice little thing the user would discover... like how you can do it in the Chrome console (I'm guessing Firebug does it too). It would be nice if you could tab through a form, fill in some strings, hit tab, jump to the first slider marker and hold up/down and so on. Obviously, it could be left/right instead.
