> I was trying to delete contents of a file and paste new content. It was nightmare for me to remember the 3 or 4 finger combination shortcuts with small and cap letters involved during the process.
Vim rarely uses multi key combinations like emacs or most other editors do. Copying and pasting involves some knowledge of how the copy registers work. It can feel confusing when you first try it, but you figure it out eventually...

The best way I can explain this is that vim is language. The process of editing in vim involves speaking this language. And once you're used to it, this language itself helps you reason about and execute editing tasks faster. It's also faster because the commands are very concise, and imo pretty easy to remember because they are mnemonics for the operations they perform. Imagine a task like selecting a string in quotes and changing it to something else with a mouse. In vim that's <ci">. c(hange)i(nside)"(doublequotes). Performing this is as instant as having thought about it.
