I am using Eclipse for PHP development. At work we use Visual Studio, so I am familiar with it’s keyboard shortcuts. In Eclipse I was quite frustrated when I was for example trying to find something in the opened document.

So I was looking for some way to change the keyboard scheme to look more like other editors. I found a possibility to use Mircosoft Visual Studio scheme. This scheme is available if C++ Development Tools  is installed in Eclipse. If you don’t have C++ Development Tools installed in Eclipse you have to install them first. To do that go to Help > Install New Software…
