Forgive me if this have been covered, but on Windows (7,8,10) and Ubuntu 14 (not sure about OSX), hitting the Windows/Super key + Number will open programs that are pinned to the taskbar in that order, so if Terminal is at spot 1, Win+1 will open it, or switch to it if it is already open, or minimize it if it is already focused, etc, etc for each program. I find this much more productive than tabbing through open windows. See the first section at http://www.howtogeek.com/124109/5-ways-to-quickly-launch-programs-on-windows/ to get a better worded description.
This works for Atom at least for launching the application, however, subsequent presses will launch completely new instances of Atom instead of switching to, or minimizing the already opened instance. Has anyone noticed or been frustrated by this, and does anyone know a workaround? Basically I just want a universal keyboard shortcut to focus the already open Atom instance - don’t really care if it is taskbar related or not - just want to tap+boom, done.
