Mapping -Arrows to selecting characters/lines

Question

I started to use vim recently, but I miss the character/line selection methods from other text editors. By default vim maps ,

Answer 1

It is definitely recommended that you don't remap this feature. Simply switching to visual mode and using v and the arrow keys is a better idea. V will select the entire line, v$ will select to the end of the line and vw will select the next word. There are many more commands you can use to select different lines and words. Learning these commands will not only be useful for selecting but also useful for editing your files more efficiently.
