joining lines

Let’s say you have two lines and you want to join them together on the same line:

I like to move it
move it

Put the cursor anywhere on the first line and push “J”

I like to move it move it

Like most vim commands you can specify a count.

I like “3J”
to move
it move it

I like to move it move it

Note: Vim puts a space between each line when combined.
