How to select all in Vim

Press gg to go to the top, V to select the line, then G to stretch the selection to the bottom. Now d deletes everything and y copies it.

The keys

Keys	What they do
`ggVG`	Select every line
`ggdG`	Delete everything, no selecting
`:%d`	Same, as a command
`:%y`	Copy everything
`ggVG"+y`	Copy everything to the system clipboard

There's no single select-all key, because you rarely need one. Any command that takes a range can use % to mean the whole file.

Selecting first is worth it when you want to see what you're about to change.
