  • When you think about it, we spend much more time reading and editing text than actually typing in text. But when we have to read and edit text, we end up having to use the mouse, or buttons or keyboard shortcuts. Why should the insertion mode be the default mode?In Vim, keys are interpreted differently depending on what mode you’re in. In insertion mode, typing ‘j’ types out ‘j’, but in normal mode, typing ‘j’ makes you go down a line.
