when i hear your question i think "why does he ask this question?"
imo you should just pick an IDE and learn coding. when you apply for a job, i don't think they want someone that knows where you press "compile" and "go" and "pause" etc... i think they want an experienced coder.
in another company we had that windows machines where we weren't free to install software... so we always had to fill out a paper for something new... but it wasn't a software company though.
copy paste usually works, yep

but it's still annoying
maybe you should specify your question more. which programming language? for some languages, some IDE's are just much better
I just thought that if all companies use something like visual studio C++ it might make things easier to code in that and learn all of its short cuts and things. I know it's not a big deal but would make transition into a real job go more smoothly.
