I might not be the sharpest tool in the shed, but I tried to find this setting for a long time without success.
I remapped switching between tabs to (mac) ctrl+tab and ctrl+shift+tab wich I'm more used to. It works good expect every 6th time or something i use ctrl+shift+tab it will open up the current file in a new window instead of just switching. It gets quite frustrating when you just want to quickly tab around. I guess it some keymapp thing which conflicts but i searched and can't find it. Anyone got any pointers?
