vim is a text editor program which is the centerpiece of a lot of people’s workflow.

while vim itself alone is already impressively good, what makes it really stand out is the amount of Keybinds it has and how well you can use them.

hjkl for left up down right, for example. Sounds complicated, takes some getting used to, but after a while, it comes natural. hjkl in particular are great for navigation as that is where ur right hand is on the keyboard all the time, so no need to move it right hand to the arrow keys.

so a lot of other programs offer vim-like Keybinds to navigate or to do text stuff. This extension being one of them.
