a-> press a<leader>-> press the leader key<leader>a-> press the leader key then a<C-a>-> ctrl-a, at the same time
In order to navigate pls don't be a n**b and use hjkl, this is not VScode
Up and Down keys have been disabled since they are sent by the terminal when the touchpad is accidentally touched while typing -- really annoying
Disclaimer: The key notation is the same used by vim
