I hate coding in the browser. On every coded functionality or testrun pressing strg+s results in saving website prompt...

Who uses manual file saving? O.o

Well that's your problem, you're using strg instead of ctrl :)
But seriously, some websites are catching ctrl-s and do their own save instead if the browser save which is great, when I press it in such an app it feels sooo good when the browser save dialog DOESN'T pop up :)
