VIM and GVIM are advanced text editors for advanced and not so advanced people. With VIM you can do whatever you need with the keyboard, without using mouse for anything; copy lines, move around the file, replace characters, etc, and with GVIM you can do the same, but with the help of the mouse to do some tasks and feel that you are working in Gedit or Notpead.

VIM is an amazing IDE with a basic(but powerful) GUI installed by default in Linux and MAC operative systems. It is designed for highly skilled profiles as it is hard to use at the beginning. However, once you dominate the basic commands, you rapidly start to feel comfortable with VIM. A huge community of developers sustain vim, and there are lots of plugins for improving the software capabilities. Apart from that, this IDE also allows modifying files in servers through SSH.

VIM is a simple text editor, but when you start to work with VIM, you increase your speed working with each text file a lot. Basically because you can do whatever you needs in a text file, like copy paste, format the code, open tabs of different files and move between them, search across the documents, replace words, and much more things that you can do without the mouse, just with keyboard shortcuts.
